There are many ways to take payment, cash, check, money order, ACH, credit card, wire transfer so you just need to understand the pros and cons or each so you can make the best choice for you. 

With a GC you loose a lot of the head ache but how much is that going to cost you?

Living beside a tenant just gives them too much access to you and your family and would just be a source of head ache in the future with the wrong tenant Why don't you just keep your primary residence for your family and buy a duplex which you rent out??

They can do ACH withdrawals from your account if you provide your account details.

Skip ahead to September/2015, and it was time for us to move to Florence, AL (or Muscle Shoals, AL) for my job (project manager/engineer).  

I prefer ACH to the appropriate account and checks in our lock box.

We are having problems with ACH returned payments, when a payment is declined and returned it’ takes 6 day form them to let us know, and that’s way too long.

Out and away in the industrial area would be great zoned for manufacturing..and possible muscle car repair.Thanks , Mike

Also, I'l be doing some of the non-permitted grunt work myself and could also benefit from a good handyman for some extra muscle.

They can last 50 years+, and *most likely* never have a head ache if flashings are done correctly.
