Or in her Will, a donation to a charity, or her financially struggling sister.I don't think I would release this amount of money to anyone without a court order--because who knows who it belongs to--it seems like part of the "Estate".

They don't have to leave any assets to heirs, but can leave it to anyone or a charity/church/organization if they choose.If there is no will, then lots of different things can happen.   

One more thing I would like to add.You need to treat this like a business and not a charity. 

They are always doing something.They also advertise with their listings that they donate to a charity $300 for every house they represent the seller (seller chooses charity of their choice) and also for every house they represent to buyer (buyer gets to choose) at the close of escrow. 

IMO just clean it and give the tenant their deposit back (assuming everything else was fine) 1) The owner knows.2) Show the bill for repair3) It's a business, not a charity.

They are going to scream bloody murder... you'll need to ask them to leave 'in order to make long overdue improvements' to the place.If you slip, ask yourself if you started into the RE business to make money or to be a charity.

Once you apprentice in these occupations and become that top tier your business activities income will give you the means to do what your talking about  travel the world  buy a sail boat  buy an airplane take tons of time with family ( for me start a charity )  or just hang out on BP LOL.    

So get a Heloc on your rental and put the entire rent to the Heloc while still maintaining some liquidity.There are multiple threads over several years debating this subject.Donate the $1000 to a charity of your choice.

, setting up an FLP, or turning it into a charity, but most of that would require planning well ahead of the sale (or concurrence from the buyer).

Is this an investment or a charity?
