Cedar Hill has a huge depreciated Market. The trick is to find properties with tenants and leases all ready in place. With that you can see your capitalization rate (your profits from your down payments after all bills are paid). You can also review lease, their rental application, and proof of deposits and copies of check. I always review the rental checks from tenants, and look at the dates written. This helps to ensure the tenants were not late.
If you would like some more help feel free to call. I would be happy to help! :)
