This will probably speed up gentrification, as gentrification is more a result of owner occupants than landlords. 

Any good resources to get up to speed?

I can PM some concerns and issues we have run up against recently in order to bring a prospective manager up to speed.

It is a lot like finding you a girl to date, you know what your looking for, you know what you want, and the blind date usually doesn't work.

If you don't otherwise allow pets, issue a notice that she needs to remove the pet by a certain date if the paperwork isn't turned in and accurate.

In the area I invest in I could buy a rentable but cosmetically dated single family home for $35-60k and rent it for $650-850.

I’ve got a ton of hvac experience so I do that inspection myself often but clearly listing the sewer inspection frequently results in the seller disclosing an issue prior to inspection date.

I have at least one BP member meeting me there, but we haven't hammered out an exact date/time yet. 

HMLs will sometimes charge 1-2 points or a fixed amount.In Texas, there is a form filed in the real property records noting the new maturity date and any other modified terms. 

On the day you close this all could be your problem to deal with, and trashy tenants paying way below market value doesn’t serve you OR them well, so I’d recommend either buying it vacant and clean, or buying it at a substantially lower price under the stipulations that the seller serves 30-day (or locally relevant number) notice to them so that on closing date or soon after it should be vacant.
