Low crime makes any location more desirable, so you can usually search crime maps.

You are usually cleaning up someone else's mess with a multi-family purchase. 

If you are vacant 1 month per property, which usually, when I inherit tenants they are bad and leave within a year, you loose $1000. 

I usually buy enough to redo a house for about $3-$5 a window at Wal-Mart. 

@Michael Mendoza If you use zillow and realtor.com you can usually get a pretty good idea of what the ARV would be.

Family members will usually work it out, especially if it is short term.  

I’ve been trying to analyze listings on the usual sites and what I receive from a real estate agent.

I've been looking at the usual suspects Zillow and Trulia but the information is not well organized I guess...

They were blaming it on a snow storm in December and sicknesses in January.Issue 4: After tenant (from issue 3) vacated; they performed a walkthrough and told me things that the tenant broke (laundry door, punched a hole in the wall, the usual). 

Have you guys found they're usually an asset or a scam?
