If nothing else, it would show the tenant you are taking their concerns seriously.I would also do a search on the property history;   it's very possible the tenants did this as well, and uncovered something disturbing about the house that is the root of this.  

Better interest rate and stuff, too.This is zoned, was priced, sold, financed, advertised on MLS (meaning you wouldn't see it if you limited your search to multifam), etc, as a single family home (old pic from google street view, I blacked out the single street address)... we had to do some property specific stuff prior to the appraisal. 

(Search the forums for that recent discussion.)

For most counties, that will take you to a site where you can do property record searches.

However, I suggest reading the company's website and Google Reviews when narrowing down your selection.

So decide first whether you want to be active or passive investor and start researching niches within the selected category and going to local REI meetings.

He also feels that I went behind his back by talking to the realtors and searching the numbers. 

Go to your county website and search for information on tax sale or property taxes.

I search, but Am finding discrepancies from site to site.

Search Yelp for PM companies, and hire the best one ASAP!
