I would suggest you get a buyers agent to assist you. There are not a ton of land contract homes out there, but some sellers are able to consider it. You are going to need an agent to help you find those sellers.
Those sellers might want things like substantial deposits, so ask your agent for advice on what you will need to to do be ready to buy.
Good luck to you!
Let me know. Otherwise, let me know what downpayment and monthly budget you have to work within and I can see if I can find a suitable property within my network.
