Monique,
Do you mean as a buyer of owner finance homes or as a seller who will owner finance?
I've purchased homes that were owner financed and they've been great. Low down payments if you can negotiate it and sometimes the owner will even finance for 30 years. There's so many possibilities. It doesn't go on your credit score as a debt and your closing costs are lower.
I bought a couple of owner financed properties with the help of realtors. It's also easy to search for them on the mls by searching for properties with the parameter 'owner financing.'
One deal the owner agreed to finance for 7 years and then required a balloon payment after term was up, but that gave me plenty of time to take advantage of the relatively low interest rate and down payment and refinance later at even better terms when interest rates dropped.
From the point of view of someone who is selling a property as an owner finance deal, it may help them tax wise by not taking a lump sum and instead taking the payment over a period of years. I've never sold as an owner finance deal but someone else can likely fill you in. :)
