She then took over the basement, locked us out of it,  and tried to claim it was hers, since she had a door from her unit that went into it!  

Therefore we immediately get to the house after the closing and make sure that all windows are secure and then have the locks changed.

It touches on a lot of the sentiment shared above and brought a really interesting concept to my attention.I almost exclusively use COC (Cash on Cash) return for my metric of choice when pulling the trigger.  

Once unit is clear and doc is signed have all the exterior locks changed including front ,side, rear door.

I can now afford to have some vacant no-rent months, but I'm having a hard time pulling the trigger on a top-of-market rent.

I paid 3 years in advance to lock in my price.

@Linda Weygant we talked about this. i think. he was wiling to do a bond for deed and even with the installments he pay taxes. i'm thinking along the lines of an agreement that will trigger in the future. also i heard that an individual can make money tax free after retirement age or 72. it that not true?

Some good leads are starting to come in and I might want to lock up a property ASAP.

Make sure you get your financial affairs in order so when you find the right deal you can pull the trigger and close on it. 

I know transferring title via quit claim deed can trigger "due on sale" however my question is if that happened could you just quit claim the property back the way it was to settle the "due on sale" clause?
