However, from my experience, many mobile home sellers (even a greater proportion than "stick built home" sellers) want/need all cash. So lease-option opportunities with mobile homes tend to be more difficult to find. Still, the only way to know is to ask.
One tip: Mobile home sellers tend to be a LOT more flexible on price than other sellers if you can offer cash. Example: I've seen plenty of mobile homes sold for 50%-60% of the asking price, even when the asking price was fairly reasonable. If you have some cash--or a relative or friend with some cash--make an offer. Even a low offer. You might be surprised at the result.
Hope that helps.
