@Rahul Gupta the absolute best way to use just about ANY vendor is to get a recommendation from another investor in your market that has already used that person/company. 

The real key is to use a title company that has done these.

As the title says, I would like to purchase a few (or a couple of larger) multifamily properties to cash-flow at least $10K per month (ideally $12K/mo.).The criteria are mainly:-B-class properties/locations (i.e. no "ghetto" properties)-Professionally managed by a reputable/trustworthy company (not fly-by-night operations)-Looking mainly in Texas DFW, San Antonio, Austin, Houston) & Wisconsin (Milwaukee and surrounding areas)What kind of investment would this require? 

Just curious if anyone has a checklist that they go through when evaluating new property management companies for out of state investing?

First company quoted us $9.5K, 2nd quoted us $4.5K, and the last quoted us $1K and had great references.

exactly, adding HOA+electricity+internet cost+property tax+insurance+flood+ flood insurance++VACASA PM FEE LOLand plus 50% vacancy rate for Airbnb rn.In hawaii vacasa doesn't have good reputation with their higher than normal PM fee.

There are a few DOB violation removal companies throughout the boroughs.

Expecting another company to change their systems and processes to accommodate you is a recipe for disaster. 

They wanted to join my company.

Or if the company is worth nothing, or nearly nothing.
