You wanted a formula of some sort, so yes, to most flippers 70% of ARV - repairs is what they want to pay, but definitely remember that that is not always in your best interest.

I have a home improvement business and I work with a few RE investors who have been sort of mentoring me, but their time is limited and I end up doing a lot of research myself.

Coming from NYC, people are experiencing more and more problems with the company and these sorts of rentals.

Take the gift of some/all lots and build long-term or short-term rentals (bearing in mind that we have only experience in long-term...zero experience in short-term rentals)-  We would have to have some sort of partner with this deal since we have no cash to build - There are not a ton of rentals in the area, so I'm not currently sure of how much a long-term could even rent for.

A bonus of sorts, but paid as interest.  

However, I'd sure like to know if there is some way to sort or filter the list based on property type. 

You can then sort it a number of ways.  

Here I thought you found some sort of "environmentally friendly" short term loan!  

We found 3 more leads that had notices on the doors.So you advise to find the owners and contact them, even though we don't have our financing completely sorted out, no contractor picked, no contracts went over by a lawyer, etc?

Iv read the 3 books that Brandon turner wrote and he does talk about this sort of thing but I wanted to get some real world advice as to what I'm going to expect when I purchase something like a 4plex.
