MHP is a very different animal than any other type of RE asset class so don't fall into the trap of thinking you can handle it since you have other rental properties. 

I am a veterinary technician, by trade, who historically make no money, but I am passionate about helping animals. 

Garland has both characteristics of Rowlett and Mesquite.

.* Damaged caused by insects and animals - A common exclusion that likely won't be removed by most carriers. 

Almost all successful business models have these characteristics. 

Plenty of investors are using direct mail to find properties that fit your criteria by contacting owners who share characteristics of owners who are likely to be ready to sell.Absentee Homeowners with High Equity are the tried and true target as many people tire of the responsibility of owning property that they don't live in.Seniors with 15+ year ownership is  another good one.

Pictures always help, as do animals. 

What characteristics are you looking for?

You really need to separate property location and characteristics (assessor data), from transaction date (recorders data), from modeled data like equity, from additional data like demographics (ie age).

Shoot me an IM and I will give you one.
