Sometimes you can finance a tiny home using an FHA loan instead of a traditional mortgage.
FHA loans help to finance both regular site built homes and mobile homes so the FHA loan company may loan you the money to purchase a tiny home.
I've heard of a few people financing tiny homes through FHA loans and others would deny them for it.
You can usually finance up to $25,000.00 for a mobile home or tiny home through an FHA loan.
Also a regular bank might finance a tiny house but not with a traditional home loan or mortgage.
A tiny home when financed by a bank would be considered an RV if it's on wheels and can easily be moved and it would be considered an RV due to the size of the tiny home.
A bank might give you an RV loan and finance the tiny home purchase that way.
Or you might be able to get a personal loan in the amount the tiny home costs and finance the tiny home that way as well.
Another option to finance a tiny home is if you currently own a regular home and have a mortgage on that home is to take out a home equity loan to pay for the tiny home.
Or sell your current home and buy the tiny home with the money and have some money leftover.
