I have worked with him as much as possible, but his situation is not changing and his ability to pay is not improving.

I know that most people have a HVAC guy but I am willing to help educate any of you to the best of my ability here on the forum or in person if needed.

I also have the ability to negotiate for lower land maintenance and insurance costs, and lower my water bill.

But it does need a communication ability that might be hard to do unless you can talk well with strangers.  

Hello I have a question and I want an outside opinion First let's begin with I dropped my rent check off on the first as it is requested And I receive a call next day to drop another check for water bill amount in witch I run over to the office to them ASAPThere are happy and everything is okay A week goes by and I notice the water bill has been taken out of my checking and not the rent so I call the office and ask what is going on and if everything was okay just because I want to make sure there were no issues Rental manager says hold on let me see if it's here and she finds is and says she is having issues scanning it to bank and I tell her I can take a new check to the office right away she asked for a cashiers check I said I do not have the ability to leave to the bank and get one my cars in shop getting worked on and that's the best I can do this second She's says ok an takes the new check and as I go to my account two days later rent money is still there and not been processed so I look online to my resident account login and there is a NSF fee and a late fee for rent in witch I don't know why when everything was paid on time and she did not call me when she knew it wouldn't scan and I had to call her Let me know your opinion I believe the fee is wrong and I should have not been charged 

Also, look at the landlord/tenant laws to confirm your ability to raise the rent to market level.

In Texas, a bill was passed approx. 10 years ago I believe, that makes it illegal for banks to offer LOC on Ag Exempt Property.

@Tom MattinsonI misunderstood your initial post and thought you were interested in formal training.While a formal education may be useful, as a property owner, I am far more concerned with your experience and demonstrated ability to get the job done.It reminds me if interviewing a young MBA graduate years ago who had no experience in our industry, but, as a result of his education, was confident he had all the answers.

That is a good area for rental property however a poor credit score may hamper your ability to purchase anything.... 

The application that they completed in the beginning should give you some insight into his ability to pay, but I would still require an updated application and new credit report on just the husband as a part of drawing up a new lease.
