On that site I could look at documents for Deeds, Mortgages, Lis Pedens, etc.  

The transaction documents are recorded in the county in which the property is located.

My opinion: do the least amount of physical work possible (leave that to others with that expertise), hire good land planner/architect/civil engineer team and you do the design/land planning (find out what lot size is best from builder/brokers), get the subdivision map approved (that's the document approved by local city/municipality that approves the single lot be divided into many smaller lots), sell the land+map to builder.

They don't pull the trigger even if the property meets the investor's criteriaObviously the agent, you plan to hire, uses digital documents and signatures to save everyone time. 

@Brady Speers, have you seen the Bigger Pockets Diary in the Pro File area, incredible documentation of a start to finish flip, budget, steps, etc.  

This would resolve the concern regarding the non-conforming unit.Any seller financing would be secured by the subject property (not my other assets).I'm not sure how the "rent back" clause gets documented, but I would like the contract to formalize that the owner can rent back her unit for as long as she like for $2000/month.

we will become just like Japan  Singapore and other countries that have to import labor.. but I suppose in a more controlled manner.. welcome in the out of country labor just document them and do keep the criminals out.. there is a seedy side to all this as you know.

The lender will help you write a letter documenting this reason.  

Purchase the note, set up w a servicer, make sure your asset is insured/protected and then let the note 'season' w the servicer for 90+ days to document a history that monthly statements and CFPB compliant late notices were sent and any correspondence is documented.   

On the other hand, if you have no clue as to what's about to happen to your money, don't be surprised if you never see it again.Finally, give yourself credit for what you do know, and get yourself a good local attorney to not only help you get, but to bring your documents to the deal.P.s.
