Talk of a conforming loan increase, and the deals roll right in . . . Arterra has just announced a new financing package. "The perfect time to purchase your new Arterra home has arrived" says today's proclamation. "Now, for a limited time, you can get attractive 4.125% financing on a five-year fixed rate loan when you qualify through Arterra's preferred lender." The fine print reads: "Rate as of 1/23/08; APR: 4.987%; 5/1 ARM interest only with 60 day lock. Based on loan amount of $417,000 and $700,000 purchase price." Bank of America, Triton Funding Group and Wells Fargo Home Mortgage are Arterra's preferred lenders, for the record. Units start in the $500,000 range, and reports suggest that the conforming loan increase could stretch into the $700's. Why not eat, drink, and be merry? Or not?
