2015 conforming loan limits are set at $417,000 for a single-family home, which is the same as the prior-year levels, dating back to 2006. Leaving mortgage loan limits unchanged helps existing U.S. homeowners to refinance; and gives today's home buyers access to government-backed home loans with low mortgage rates.
When FNMA and FHLMC limits don't cover the full loan amount, the loan is referred to as a jumbo mortgage. Traditionally, the interest rates on jumbo mortgages are higher than for conforming mortgages, however with GSE fees increasing, Jumbo loans have recently seen lower interest rates than conforming loans.
