Lead paint testing requires no supervision or follow-up inspection.

I did a test to see interest at $3,000 that got some good candidates, but didn't take them through the whole qualification process because it's not ready to rent yet. 

They tested the appliances thoroughly and offered a one-year guarantee.

This could cost around $500 to $1,500 per unit, depending on the size and complexity of the project.Certifications: There may be additional costs for certifications (such as HERS ratings) or third-party testing to verify the energy efficiency of each unit.For a 90-unit project, you could be looking at costs in the range of:$45,000 to $135,000 for energy modeling and certification (depending on the cost per unit).For a 112-unit project, the costs would likely be:$56,000 to $168,000 for similar services.Tax Credit Calculation:If you meet the energy standards, you can claim up to $2,000 per unit.

For the son to qualify for the $250k exclusion, I believe he would most likely need to meet the ownership and use test, meaning he needs to own and live in the home as his primary residence for at least two of the last five years before the sale.

My ultimate goal is to become successful with my real estate investments so I don’t have to rely so much on my job and be able to spend more time at home with my soon to be wife and future children.

Ultimately, it's difficult to confirm the identity of the borrower. 

When analyzing properties, it's helpful to run a rental stress test to see if the deal can withstand unexpected challenges.

I ultimately did not do it but I'd be interested to hear if anyone tried that program or knows of anyone who did.
