@Bill Regan I reached out and it turn out someone snapped that deal up, it might have even been someone from this site!

Welcome to the site Andrew.

Most investors on this site are residential with a few commercial sprinkled in so when BP develops software to use that is likely the main focus residential first.There are tons of software for commercial analysis to use out there. 

You could also consider owner financing if you wanted, but that may be more complicated.

As to them having custody of a grandchild, that makes it so much more complicated, hopefully someone else can step in and help with the child during this time of their lives. 

Stumbled upon the site after I found J Scott's book on Amazon.

Anyway its somewhat complicated - so buyer beware    - but overall a sewer system should be great for the area as in-n-out, trader joes, etc.. will be able to do traditional builds rather then complicated septic system/environmental reviews etc.   

When I inquire with lenders I give them the following info:Property: Investment rental (non-owner occupied SFH)Credit Score: >740Loan Amount: $80-$120KRequired LTV: 80%While im on a site like Zillow looking at properties, Ill often try to to look up rates (and APRs) and after entering in the information above  I see numbers in the mid to high 4s.

@Nicholas Cooley there are a number of tools on the site that can assist you.

A good primer on tax-advantaged accounts (IRAs, HSAs) can be found on the Mad FIentist site (https://www.biggerpockets.com/forums/846/topics/563476-ep-18-accessing-retirement-funds-before-59-1-2-w-the-mad-fientist, https://www.madfientist.com/ultimate-retirement-account/).My background: I worked for many years as an independent contractor through a temporary help agency.
