We currently still have the AK condo rented out and have bought a house in Phoenix that we are currently are fixing up. 

Consider financing options like hard money loans, or FHA loans for house hacking, and focus on areas with strong rental demand near the MA/NH border.

It's super affordable and you can still find houses for 120-180k here!

You could tell them to cancel the listing and you will find someone else to list it after a month not 4 months (the market take is subjective too, all dependent on what your house has compared to others, where it is located, the size of it, and so many other factors).

If she went to buy a house and applied for a mortgage, I think the lender would say the same thing aka you don't qualify until you get this removed from the credit report.

Now, the house that is about to refinance, I am thinking of turning into a MTR for traveling nurses, or other professionals as such.

When we were getting our own kitchen remodeled in our house a few months ago, we asked the contractor if he would be able to possibly fix that cupboard door at our rental property.

as a flipper, with the participation of a wholesaler and a hard money lender, what actions should I take BEFORE I close and buy a house (tell me step by step please because i dont really understand the sequence of events) and also please tell me when to do due diligence to make sure how much does it cost to renovate the house and is it worth buying this house?

So the line is a shared private line between the 8 houses. 

But you also SHOULD have some vacancy and some capex on an 80 year old house.
