And it's the same news.
Most mobile home sellers want cash. But many buyers (like yourself) can'd do all cash. Further, while new/newer homes can often be financed, it's quite difficult to get financing on older mobile homes--say, more than 5 or 6 years old.
As a result, a lot more mobile home sellers end up offering owner financing than you'll find with regular stick-built homes. These aren't usually rent-to-own...for a few reasons. First, a lot of mobile home parks don't allow renters. A rent-to-own is considered a rental. On the other hand, if you buy it (with owner financing), then you are the owner.
If a park does allow renters, then you could do a rent-to-own. However, you'd be in a better position--more protected--buying with owner financing. And it's pretty much the same to the owner. In either case, he's not receiving most of the cash up front.
Tip: When talking to sellers, find out how much cash they really need. For example, you might find a home for $30,000, and it might be a good value at that price. While the owner certainly would prefer all cash, he/she might not need all cash. Maybe the person needs $5,000 to move to Florida and stay with a relative. Maybe the person needs $3,000 for a car repair, but plans to move in with friends. That instantly reduces the amount you have to come up with--dropping from $30,000 to perhaps $5,000.
Also, some investors can put together a deal. I've done that myself. The way it works is: The investor buys the home for all cash, often at a substantial discount. Then he sells it to you with seller financing. Example: The home is for sale at $30,000. The investor makes a cash offer of less than $30,000, which is accepted. The investor offers the home to you for $1,000 with monthly payments of $512 for 7 years. (That's 12% interest.) The investor makes the money by having bought the property for less than $30,000.
Hope that helps.
