It is located in some of the newest developments on the north side of Katy, TX 77493 (I am not sure if I can post a link to the Zillow page or provide the address because I don't own it yet).

Keep the text from the “reliable” tenant that shows they provided the addresses you sent the letters to. 

I know many landlords set a credit score threshold around 580-600 for Section 8 tenants since the program provides a rental guarantee.

Providing a simple and easy move-in process can help create the best experience for new tenants.

I have used avail.co in the past with great success but it appears this software and others no longer market on zillow which I know to provide a lot of leads in the past. 

I always advise to run a business for 3-6 months without an entity to see if it something you are making money in and something you want to continue doing.Once you have 3-6 months of activity, you have more information to provide to an accountant regarding income so he can provide suggestions on entity type.Best of luck

Is it the same as land trusts ?

How comfortable are you with the idea of trusting agents to lead showings versus allowing prospective tenants to tour properties on their own? 

If you have access to someone who is ready to trust you with their asset, do right by the owner and go for it!

The more time you spend talking about other options and try to build up the negatives, the less time you are spending on what you fell are the positives of your own idea.If you believe that you are onto a great idea using L2P option contracts and forming partnerships where someone else provides 100% of the money while you provide 100% of the real estate-related functions, then start it up and make it work.
