Without too much detail I had to quit my W2 job 2 years ago to care for my disabled son and my wife is still working.

Can someone explain the details of selling a house to a child?

If possible, meet the appraiser to provide your rehab details and comps.Also, out of curiosity, when did you purchase the property and when are you looking to refinance? 

I offered a month’s rent in addition to what was reasonable for loss of use of 7 weeks of garage and 2 weeks of kitchen/bathroom unavailability (adjusted for back rent for unauthorized pet) but no response from tenant other than pursuing legal option unless I share Landlord insurance details.

Here's a bit more in detail about how rates are calculated for DSCR loans:1.

This is specific to this, I have the detailed 411 on this, including full background on seller, why selling, how things have gone, maintenance history and recent updates/upgrades such as the newer roof, HVAC etc etc etc... 

DSCR loans can be helpful for the rentals you have depending on the details.

As a limited partner, you would be able to participate in the project without being involved in the day-to-day operations, while benefiting from the potential profits upon completion.If this sounds like an opportunity you would be interested in, I would love to discuss further and provide additional details on how we can collaborate.Looking forward to connecting soon.

If her goal is to provide some of the proceeds to her ex in good faith, she can simply sell the property, have a tax professional estimate the taxable gains.

You would need to do a detailed write up of both you and your brothers situation to get any useful info from here.
