I listened to a real estate audiobook where the author did something similar - he was in an owner financing contract and if I recall correctly, he signed a separate agreement with another individual so that their payments covered his monthly payments.Really appreciate any feedback on this idea.

What documents do they require, what credit scores do they allow, how do they verify previous rental history, etc.?

Every state where we do business has laws on the books that provide for "winding up" authority... that is the sole surviving member(s) of an LLC or director(s) or shareholder(s) of a corporation are vested with authority as trustees of the entity's assets to sell them as part of the dissolution process.

I dont understand how people can lie on official legal documents and get away with it.you can argue that different people calculate sqft differently but the margin of error can explain 100sqft (the condo is not that big). also no unit as ever been listed for over 1300sqft in the history of the building!

Also, since you have no investment history a lender is most likely not going to give you any credit for the potential income of your planned investment.You may be able to get a private lender or perhaps a bank that does some portfolio lending to give you a chance.
