High costs are still a big barrier to prospective customers said Alan Gibson principal at Maine-based builder GO Logic where a shell for an ultra-efficient two-story 1400 square foot home with three bedrooms can cost around 600000. трипскан вход Homeowners also need to factor in additional costs like buying and developing a suitable plot of land and in some cases getting access to water electricity and septic Gibson added. https://tripskan.cc tripscan войти The way to bring down costs Gibson believes is more panelized multi-family housing. “It can be done so much more efficiently” Gibson said “and there’s a lot more repetition” for the developer making the process faster and less expensive than custom multi-family builds. Goodson the homeowner in Maine was able to save big money with his engineering background and penchant for DIY. He installed a rooftop solar system and electrical improvements himself saving hundreds of thousands of dollars in the process. He wound up spending around 500000 in all which he estimates was 200000 less than he otherwise would have. “It’s a big number to swallow I’m not making light of that at all but it’s not that far out of what’s reasonable” Goodson told CNN. It’s also not considering the long-term savings he will experience with no utility bills. He was also able to take advantage of federal tax credits that reduced the cost of his rooftop solar which saved him more than 10000 on his panels. Those tax credits are now endangered with House Republicans’ tax bill. “That was huge” he said. “It’s fairly unfortunate they’re looking at doing away with it.”

Americans nearing retirement and recent retirees said they were anxious and frustrated following a second day of market turmoil that hit their 401ks after President Donald Trump’s escalation of tariffs. kraken14.at As the impending tariffs shook the global economy Friday people who were planning on their retirement accounts to carry them through their golden years said the economic chaos was hitting too close to home. kraken4 Some said they are pausing big-ticket purchases and reconsidering home renovations while others said they fear their quality of life will be adversely affected by all the turmoil. “I’m just kind of stunned and with so much money in the market we just sort of have to hope we have enough time to recover” said Paula 68 a former occupational health professional in New Jersey who retired three years ago. Paula who spoke on the condition of anonymity because she feared retaliation for speaking out against Trump administration policies said she was worried about what lies ahead. https://kra4l.cc “What we’ve been doing is trying to enjoy the time that we have but you want to be able to make it last” Paula said Friday. “I have no confidence here.” Trump fulfilled his campaign promise this week to unleash sweeping tariffs including on the United States’ largest trading partners in a move that has sparked fears of a global trade war. The decision sent the stock market spinning. On Friday afternoon the broad-based S&P 500 closed down 6 the tech-heavy Nasdaq dropped 5.8 and the Dow Jones Industrial Average fell more than 2200 points or about 5.5.

Ich bin mit Interesse aber ohne gro?e Erwartungen an das Projekt herangegangen. Ich wollte es einfach mal testen. Und am Ende bin ich geblieben – auf lange Sicht. Mich hat alles angesprochen: die Rendite die Einfachheit die Offenheit. Aber das Wichtigste war die Community. Echte Menschen mit denen man nicht nur uber Zahlen sondern auch uber Strategien sprechen kann. Ich habe sogar neue Bekanntschaften geschlossen. So etwas habe ich in der Kryptowelt noch nie erlebt.

The waterways in Texas Hill Country have carved paths over the centuries through the granite and limestone shaping the rocky peaks and valleys that make the region so breathtaking. порно анальный секс When too much rain falls for the ground to absorb it runs downhill pulled by gravity into streams creeks and rivers. The rain fills the waterways beyond their banks and the excess overflows in predictable patterns that follow the terrain. Governments and waterway managers know what will flood first and who will be threatened when a truly historic rain event takes place. https://scaud.info/blog/post/zhit-horosho-v-life-good-legenda-ili-realnaya-istoriya порно жесткий секс The Federal Emergency Management Agency maintains a database of flood zones throughout the country. It maps the regulatory floodways — the places that will flood first and are most dangerous — and the areas that will flood in extreme events. The Guadalupe River flood was a 1-in-100-year event meaning it has about a 1 chance of happening in any given year. Extreme flooding is happening more frequently as the world warms and the atmosphere is able to hold more moisture. Texas has already seen multiple dangerous flooding events this year and the United States overall saw a record number of flash flood emergencies last year. More than an entire summer’s worth of rain fell in some spots in central Texas in just a few hours early on the Fourth of July quickly overwhelming dry soils and creating significant flash flooding. Central Texas is currently home to some of the worst drought in the United States and bone-dry soils flood very quickly. Camp Mystic is a nondenominational Christian summer camp for girls in western Kerr County. The camp is located at a dangerous confluence of the South Fork Guadalupe River and Cypress Creek where flood waters converged. Camp Mystic has two sites both of which overlap with either the floodway or areas the federal government has determined have a 1 or 0.2 annual chance of flooding. The camp confirmed that at least 27 campers and counsellors perished in the floods in a statement on its website. It said it is in communication with local authorities who are continuing to search for “missing girls.” Ten minutes north on the South Fork is Camp La Junta a boys camp. Some of Camp La Junta’s property also coincides with areas known to flood though several of its buildings are located in the lower-risk zone or outside the flood zones entirely.

A? ship that US and Philippine forces planned to sink beat them to it. mgmarket4 at A former US World War II-era warship which survived two of the Pacific War’s most important battles was supposed to go down in a blaze of glory in a live-fire exercise off the western coast of the Philippines as part of annually held joint military drills. mgmarket4 at Instead before the bombs and missiles could fly it slipped slowly beneath the South China Sea Monday morning age and the ocean catching up to it before modern weaponry could decimate it. The ex-USS Brattleboro was to be the main target for the maritime strike MARSTRIKE portion of the annual US-Philippine “Balikatan” exercise which began April 21 and runs to May 9. mgmarket4.at “The vessel was selected because it exceeded its service life and was no longer suitable for normal operations” according to a statement from the Armed Forces of the Philippines. Chinese coast guard offices display their national flag on a tiny sandbar in the disputed Sandy Cay in April 2025.

A report from the official Philippine News Agency PNA said it was to be hit by US and Philippine forces with a combination of anti-ship missiles bombs and automatic cannon fire. But as the 184-foot-long vessel was being towed to its station for the exercise 35 miles west of Zambales province on the northern Philippine island of Luzon it took on water the Philippine military statement said. mg3ga at https://megaweb-16at.ru “Due to rough sea conditions that we are currently experiencing in the exercise box and with its long service life as is expected she took on a significant amount of water and eventually sank” Philippine Navy spokesperson Capt. John Percie Alcos said according to PNA. He said the vessel was not damaged while being towed. The ship sank quietly at 7:20 a.m. local time near the spot where it was to be obliterated later in the day according to the Philippine military. Other elements of the MARSTRKE exercise would go on the military statement said. The Philippine and US joint task forces “will rehearse virtual and constructive fire missions” the statement said without detailing what elements were still scheduled as part of the drill. “The combined force will still achieve its training objectives” it added. mgmarket3.at https://megaweb-16at.ru The Philippine military said there was no environmental danger from the sinking as the vessel had been cleaned before being towed out for the exercise.
