There are a few loans that will wrap in the renovation costs into the purchase price and finance them together. Here are the few that I know of:
Wells Fargo Purchase & Renovate Loan. You will have to check and see if this loan is still available with Wells Fargo. Here is the link: https://www.wellsfargo.com/mortgage/home-improvement-loans
Home Path Renovation Loan: This is only available if you purchase a FannieMae foreclosure. Here is the link to their information: https://www.fanniemae.com/content/fact_sheet/homestyle-renovation-factsheet.pdf
The most common is the FHA or HUD 203(k) just watch the interest rate and mortgage insurance. It can be a killer. http://www.fha.com/fha_article?id=37
There are others that are offered by local banks, but these are the most common.
