But while having grown up in similar areas,.I did not have the proper knowledge or protocols to deal with the tenant base...and so I lost money on a number of those investments.

If you have a net worth to protect, I would just work with a proper asset protection attorney to discuss what you need to do.

EDIT: To clarify, have your agent schedule a showing and go through the proper steps to go in vacant houses, don't just "go into vacant houses"

I have SFHs and a few small apartment complexes, but this would be a first for me.Quick run-down:45 lots, with no room to expand18 full - 15 POH and 3 paying just lot rentPublic Utilities, proper zoning, paved streetsSmall town, around 45 minutes from any sizable town; around ~2,500 residents that are mostly blue collar, lower incomeI believe lot rent should be around $250-300 per spot once full and stabilizedCurrent asking price is around $200k, with expenses running around 35-40% of gross incomeMy initial plan would be to give all POH to the current tenants if they agree to re-sign lot leases and update all utilities and other facilities as necessary in order be prepared for additional homes being moved in.

Do they have all the programs to properly take care of all their needs?

I live in the East side of Tucson and since moving here in June of 18, notice that investors buy these houses at a price that doesn’t allow enough $ for a proper rehab.

Proc. 2002-69 and 2002 C.B. 831, a husband and wife who are the sole owners of an LLC and reside in a community property state can choose whether they are treated as a partnership or disregarded entity.You have to understand that tax and legal matters are different. 1) for tax, you will be reporting on your personal return, Schedule E.2) for legal purpose, LLC is a separate entity, and it has to be treated separately from your personal finance.

Properly screening them.

I'm curious as to best practices people might use to evaluate market value properly.
