How feasible is it to have an offer accepted utilizing seller financing for non-REO properties with the intention to flip?

There is also no target right in terms of an asset, and you need that.That's a fair point, I don't want to get in over my head but I would like to get some passive income rolling...I just need to know if there's any actual feasible way to get me started in this business at my income level.

Looking for an easy solution that allows for electronic tenant screening, lease signing, and document storage.

A close-to-move in ready property is much more feasible for OOS.

Everything from Feasibility work through to the final clean.

MHP, Warehouses, Offices, Retail, 3N, Storage, is rarely even mentioned.
