So whenever the buyer wants to refinance or sell the property my lien comes up aswell and that's when I'm taken care of? 

Now the situation has occurred that we need to rent the house out in order to help pay for his long term care expenses. 

And do they care if I do rent by the room strategies?

That would take the pressure off Tenant A and let Tenant B know you care.

I look for properties where the owners don't much care and just want money and then I pay cash with quick settlement. 

She would be putting all the cash down for the property and I'm a contractor and would take care of all of the rehab work along with finding the house, dealing with real estate agent etc. how can we make it so that it would be 50-50 ownership of the property and all future profit? 

I don’t have experience in either market, but be careful with markets that are already booming or at their peak.

You should be careful with unrelated occupants.

It is a perfectly good fridge, tenants don't care.

If the tenants don't care for the pool properly, it could cost you thousands to fix.
