🧐Finally under contract on your dream home, yes!

From what I'm reading here, and we immediately sought legal counsel on this, they're totally free to move out anytime they want.

This involves finding undervalued properties, securing them under contract, and then selling the contract to another investor.10.

Quote from @Jake Hughes: How do you write a contract for deals when using OPM?

Do not rely on it for legal advice.

My guess is You will need to go through a foreclosure process in this situation as a legal remedy.

Once you have the property converted to two legal units, it's going to depend on business vs. personal useage. 

Inspections may cost more upfront, but they can save you from significant headaches and unexpected expenses down the road.Negotiate Hard: Use inspection findings as leverage.If the HVAC is near the end of its life, negotiate a credit for its replacement.If the cast iron plumbing is deteriorating and needs replacement, ask for a credit as well.Sellers often prefer negotiating credits over doing the work themselves.To give you an example: I was once under contract for an old house priced at $170,000.

Therefore your contract needs to adjusted accordingly.
