Avoid properties on main streets (traffic noise, avoid homes near freeways (smog/traffic noise), avoid homes without garages if most other homes have garages, avoid being in airport flight paths, avoid over building or over rehabbing for the area comps, know how to properly and accurately estimate ARv and rehab costs, and have money lined up in advance.

I have now sent 3 or 4 emails to my rep with no answers, and then sent a message to their main email address a week ago, and still haven't heard from anyone.

Any illegal activity like drug dealing, prostitution or gambling can attract unwanted elements.

Mainly we invest in 2/1-3/1s (if they have 2 baths that's a plus but not a deal breaker).

@Dmitriy Fomichenko if you don’t get any tax benefits like depreciation, what are the main advantages of using SDIRA or solo 401K for real estate purchases?

We still have land to build on and have all the infrastructure set up, mainly from our prior builds, to make it even cheaper. 

thanks for the replies, to clarify a bit more, I'm mainly looking for an agent who can be my eyes and ears in the case I'm not able to be there in person to view the property.

This is mainly if you want to be hands on with your property, which I want to as well.

The main difference is that you can't deduct the principal portion of your mortgage payment (even though it affects cash) but you can deduct depreciation (even though it doesn't affect cash). 

If the tenant does not dispute the deductions or the amount due and payable to the tenant within sixty days after the itemized list and amount due are mailed as prescribed by this subsection, the amount due to the tenant as set forth in the itemized list with any amount due is deemed valid and final and any further claims of the tenant are waived.”To further address your specific concern, there is a particular element in the quoted section of the law that requires an action from the tenant.
