Criticism 3.

If someone wants to share their opinions on ways to narrow down / categorize / filter the parcel list using public data sources, I'd be happy to share my thoughts on the technical feasibility.

An appraiser could probably provide better context on professional standards in this area, but I think 90 days is a nice to have not must have.Are you using realcomp MLS data or public sources?

There are a million parks - don't get excited over any one individual one.You haven't told us a few critical factors in valuing your park:1 - What the lot rents are2 - How many lots total there are3 - Are any of the park owned homes vacant, and if so - how many are vacant?

However, I am researching every property through neighborhoodscout and other sources of information to get a feel of what the neighborhood feels like.

Listening well is one of the most critical.

Occupancy is critical with first mortgages, and in the 1st lien world there is usually a higher chance of vacancy (and if that is the case you're usually exiting through the property as opposed to 2nds where you would usually exit through the borrower).

BP is an excellent source of learning.

Cities & Counties are constantly seeking new $ sources.
