Over the course of ten years I've supplemented my income with about ten deals and now that I'm settled I want to take it more serious, maybe even full time.

Let the tenant leave, list the property correctly, write the lease clearly (not all generic leases from attorneys cover unique property issues) and get your neighbor a new neighbor. 

I'm looking for additional avenues to supplement my income.

There's a wealth of knowledge on this site about a wide range of topics, who knows it may lead me to other opportunities to supplement my financial business.So enough about me I just want to say hello to everyone!!

I don’t fully believe in mass generic marketing materials sent out in hopes to get the attention of one.

Every piece of advice I've seen says to get forms specific to Texas; don't use generic forms. www.LoneStarLandLaw.com is a fantastic resource for information.

This is generally a part time , supplemental income job.

Im mainly looking for more passive ways of building sustainable long term wealth, not interested in the overnight success or endlesa days rehabbing homes, as this would be supplemental income.Thanks and look forward to learning more!

Honestly, I think you're going to have to come to terms with the fact that your time together will decrease until he can supplement his 2nd jobs income with his earnings from real estate...  

You want to be as thorough as you can especially if it's going to be supplementing income for your father, if your going to buy a small townhouse or condo that needs work you will want to do the same thing as well how much in repairs will it need how much of a down payment do you want to have etc. the numbers are very key in doing any real estate deal so make sure you try to be as accurate as you can in knowing how much it's going to cost in executing your plan Thanks, Michael
