Owner financing a single family home in Texas?

I have a tenant who wants to buy my house with owner financing in the State of Texas. The house is fully paid. They are looking to put down 10% from the sum of 175K. They want a loan of 15 years from January 2011. I have 55, which means it will be 70 before it is paid. What kind of interest rate should I charge. Texas Homestead Act to protect them in case of excluding from the property. What is the average time to leave? Is 10% to cover it? Buyers Insurance pays the market price … correct? Quickclaim is interesting. Do I need an attorney to write the contract?

Is there any reason can not get a traditional mortgage? It would be great banner for those looking for owner financing. I do not want to be bad, but it seems that hope is dying and not have to pay …
