The easiest financing to get now is USDA loans.
Find out which areas near you are covered under USDA – then go get some deals there if you insist in selling to retail buyers. You will have to jump through a lot of hoops to sell to a buyer who is getting financing. It will be stressful and very time consuming.
It is much better to buy with seller financing then sell with seller financing. Or buy subject to the mortgage then rent out/sell with seller financing. Or do master leases. Or do wholesale deals.
Any kind of deal that does not require selling to a retail buyer will be MUCH EASIER.
