You can't do a 1031 exchange on a residence, only on investment property.Even if your MIL waives her commission, the buyer's agent won't. 

Chase just sent me a credit score of 800 and a limited appraisal of 475k on my residence, which is owned free and clear.

This takes the pressure off to resolve immediately.

She is more than 2 weeks late every month she has lived at the residence (also, she is an alcoholic and hostile with the other tenants, but that's not a legal reason to terminate tenancy).

Would I be able to utilize program benefits or start applying without being a resident of the state?

So, I would need to do a 3.5 percent down on the second/ new primary residence home.

My primary residence is paid off, and I have an open HELOC on it.

You can always pressurize the domestic water lines with air and check that way . 

The east facing balcony has great sunlight in the morning.Some Shared Amenities include: Pool, Tennis Courts, Sauna, Beach Access, Car Wash, Heated Underground ParkingTenant to pay electricity utility.I've recently mailed 45 Postcards to all the other tenants in the Condo building offering a $200 Referral.

I am moving out of my primary residence in a few months and will rent it out.
