The set of circumstances that create the motivation you need are lower financial literacy, very little financial flexibility, a general tendency to look for easy solutions.

As if having someone living there and having the owner pay their rent for them is a better solution. 

The more reasonable solution since construction/trades are still able to work is to move forward.

The solution was easy, get up an hour and a half every single morning to work on growing our portfolio.

My contract stated that if during the rehab the contractor notice something that was possible toxic he will test and notify the customer.

Assuming he hasn't I would ask the tenant to come up with a solution on how to handle the situation because you still expect the rent to be paid.

It may be best to consult with an estate/family planning attorney to make sure you come up with the best solutions based on the laws of where you reside.

If you built the garages, installed the pool, etc without permits and inspections, you'll have many more problems with getting those passed by your township than you may think.The solution I would recommend is to have your parents refi, put the property into a trust, you can be a co-beneficiary, and when you can afford, give them whatever money you have agreed to and have them quit claim their beneficial interest in the trust to you.I am a realtor, not an attorney, so please seek out a qualified attorney to get you set up. 

What's your proposed solution?
