Hi Melanie,
A good lesson we learned several years ago was about getting properties delivered vacant. If you intend on managing a building or buying a building that is coming vacant as a part of escrow, double check that it is ACTUALLY VACANT before you close or take over the units.
It seems like common sense but you'd be surprised at what agents will tell you to get you to close. Only trust your own two eyes!
We were buying a duplex in Los Angeles that was to be delivered vacant per the seller. The units were occupied by the seller and his daughter. A couple days before the close of escrow I swung by the property and saw the seller was gone from his unit but there were still belongings in the second unit. When we brought this up to the agent, he said not to worry and they are the seller's daughter, they know they have to go, and will be gone in the next day or two.
Being inexperienced, I took his word and closed the deal. After the closing, I showed up with my crew to change the locks only to be greeted by the sellers daughter who claims she was unaware of the sale and is not leaving!
Along with all the legal action that took place, we also had to pay extra money to the seller's daughter to leave, physically move her out, and find her a new place. We did all this which took precious time and money to solve.
Needless to say we always triple check a property will be vacant before closing escrow now or hold back significant money until it is.
