When their lease comes up, I don't let them renew and start with a fresh tenant.If it's attracting pests, interefering with neighbors, or causing damage to the home, they are given a verbal and written warning with specific instructions for cleaning, a deadline, and a scheduled follow-up inspection to confirm compliance.

Here is a list of a few things I’ve heard on BP podcasts that investors should look for when it comes to finding hidden potential for value add.

An ADU, a room with a separate entrance, a basement..often the real return is hidden beyond the conventional assessment or projection. - Not all deals are created equalInvesting is a fun game.

Introduce yourself and hand them a letter that includes instructions for payment of rent and how to report maintenance, ask questions, etc.

BUT caution -- Look out for hidden / made up closing costs and clarify it before you pay the earnest money. 

You will come across hidden repairs, this is always a good number to add to all construction projects, as there is ALWAYS money hidden in the walls of a construction project.Second; keep in mind an order building will need constant updating and more repairs over time than a new construction.  

Contact your county office and ask them how you can find the owner of a parcel and they can instruct you from there.

Wholesaler should put you on email chain or some other communication with attorney so y'all can discuss title, ALTA, closing date/time and wiring instructions.

You can also look at their credit report to see if they have any riskly loans, do they make payments on time, what their credit score is, do they have any collections or judgements or bankruptcies, etc.Here's a pretty good instruction manual for application screening: https://www.biggerpockets.com/... 

Additionally, you should also consider conducting thorough due diligence on the property to ensure that it is a good investment and that there are no hidden issues or liabilities.Overall, it's important to approach any real estate transaction with caution and do your research before making any commitments.
