My advice on sub to is as follows1- COMPLETELY understand the process, implications, liabilities, and possible outcomes before engaging or attempting to engage in a sub to transaction2- Complete disclosure going so far as making sure the other part understands the transaction and possible consequences3- Utilization of an attorney experienced in subject to transactions for setup in such a way that provides some protections in case of default or in case the note is called4- Have a backup plan in case the note is called5 - only use for property that has a TRUE positive cash flow unless the buyer has substantial reserves I myself have purchased 8 properties subject to, but 5 of those were commercial properties which often have notes where a subject to is allowable.  

Several were fully permitted and never developed because there were no buyers for the energy at the cost that was needed for the private companies to make a profit--and this was in a state with rolling blackouts during the summer. 

Pay a Title Company to complete a Title Report3.

I took Private Money Broker in 2018 through his company.

Need to watch out for utilities like water meter, electrical, gas, and sewer.

You have to make sure that whatever company you choose will maximize your profits. 

A reputable title company will keep things on track. 

the insurance companies are not charities; they deserve to make reasonable profit for providing the insurance.  

Type of construction materials for the build(block/metal frame/wood frame), separate utilities, finishes, tech, cleaning crews, any tips and tricks would be HUGE! 

In my opinion, even if you partner with a local PM company or turnkey operator your returns will drop significantly.
