For all of those affected recently by Hurricane Harvey and the impending Hurricane Irma. FHA does offer a lending program that can help you buy a new home with no money down. FHA 203H loans are designed specifically for disaster victims who are displaced from their current home. Very easy to qualify provided that you can provide documentation, ie FEMA application or Insurance Claim forms to prove your hardship.
A number of people affected by the storms did not have Flood insurance in place. If that is the case then an FHA 203K or Fannie Mae Home Style loan can be used to finance the renovations into your new mortgage. Make sure to meet with a contractor first and get a bid so that you know what it will cost to accomplish your goal.
These are tough times for those affected, and this has affected my own household. Thoughts and prayers go out to all that are affected!
