Although from the landlord's perspective, it appears that the price has been dropped significantly from where they started, it still may not be enough to meet current market levels where demand is sustainable. 

@Tayvion PaytonDFW's real estate market is thriving, with high demand for long-term and short-term rentals.

I know that I can not deny an ESA for a tenant, but can I deny their guests from bringing ESA animals when they visit or stay overnight?

Two different animals really and I don't see creative financing is typically a reality with either option.Typically for tax liens and deeds you will need cash to be a player and cash that you can tie up for 1 year or two at minimum.   

However, their 38 page Prop Mgmt Agreement for OneRate is daunting--it lists many exclusions to their obligations such as any damage caused by force to a surface (whether from tenants, animals, roots, wind or other force of nature, etc).

Enhancing the property can increase rental income and property value.Smaller Units: Consider investing in properties with smaller units, such as studios or one-bedroom apartments, which often have higher rental demand and lower per-unit costs.

I guess if demand is relatively high in your area, you can elevate your requirements as high as you want. 

Research Texas markets with affordable prices and strong rental demand.

Most recently a tenant moved out and left the house full of roaches and another one just had an animal in the attic that somehow knocked down the ceiling light in the kitchen.

So much demand from out of state investors drive the prices up for 2-4 units.
