I plan on living in it 12-13 months, then converting it to a rental, and buying another primary residence.

But this I do know:  every single AVM I have tried from Zillow and other is way off on my own personal residence by a big margin.

My background in real estate is more on the loan side thanks to my job however I own my own residence.

I just did a single family residence deal there earlier this year but it was a 1 unit so loan limits are 554,300 as opposed to yours which is $709,600 so it looks like your loan amount is below that which may help you get financing if you're considering a refinance.FHA allows a cash out to 85% of current market value so if you believe you're at 603,000 loan amount then you'd need a min appraisal of 709k or so to refinance this home into a conventional loan if you're trying to remove mortgage insurance.There are lines of credit to 89.90% or 90% of your homes value if you're interested in having access to your equity (if the property appraises high enough).To address your questions:1) If it appraises high enough yes you can remove monthly MI and you can use a line of credit 2nd to access your equity (this would be your best bet).

First negotiate, selling price WILL be adjusted to account for getting code compliance on everything.Then you get the contractors bids for the workProceed only on the buyer's concurrence.Should I agree to a higher price repair, as in, "Offer is $115,000 minus repair costs as estimated by a qualified contractor"?

Since I was in Texas and planned on staying there, I found out that I was qualified to take a test and get a real estate broker license, so I took the test and got my license.
