Ideally, my list would meet the following criteria:Property built after 1980Last sale on or before 2014Property is 20,000 - 80,000 squarefeetBuilding is multi-tenant (vs single tenant)Owner of the building (or LLC) is an individual or couple in their 70's or olderMy question is primarily about finding the last 3 bullet points, ESPECIALLY the tenancy (multi vs single). 

As far as the individual expenses go (excluding utilities) I start with 8.34% or $187.65 (one month rent) for Vacancy. 

They have more to gain because they can use the help, they might not be too busy to teach or let you participate in the GP duties, and hungry enough to give up significant equity if you source a deal.  

This is more efficient than individual LLCs for every property but still isolates liability.

Spend time reading profiles and connect with individuals. 

A high school teacher of mine who is teaching economic and finance got me thinking of how to invest my money.

In any case, always look at the individual deal.

Looking for an individual or firm who is well versed in liens, foreclosures, probates, quiet title, ect.

I'll add this is a Baltimore single family home that would ideally be rented to 4 different individuals, who would share the living space, near Johns Hopkins University.

As far as taxes go: I know individuals who flip houses get taxed out the a**.
