The property is located in Texas how much can I expect to pay more or less for this complex situation? 

That being said, there are other factors to consider like the location in area.

Checking out their track records in specific locations is key.

Location!!!

Growing population, great employment opportunities, steady appreciation etc.The best amenity has been location.

Because the existing house was too low the developer followed the rough location of the old sewer line and installed a new sewer line to connect to the existing house. 

Do you know the bed bath count and location class?

Appliances supplied mean better rents and a higher quality tenant.The location of the rental and the type of tenant you want will dictate what you supply.Finding a good supplier of new appliances will get your cost down to the point that used doesn't make sense.

Try to look for well-located properties near employment centers.

Where we live housing prices are relatively cheap compared to if the house was in a different location.
