Your land drainage has a lot to do with how well it drains off surface moisture which includes your aerobic system sprinklers as well.  

On the surface positive cash flow of $215/month on a SFH is not bad but the bigger question is can you increase the profits at all.

They required "skin" in the game and I didn't have the 20k to put down, so I borrowed that too.

If you can build up some savings and put it all on the line with your doctor friend, it puts some of your skin in the game too.  

You are asking a stranger to lend you basically all the money for a deal with no experience and no skin in the game. 

@Libbie Grant Welcome to the wonderful world of real estate investing where there are a million ways to skin the cat, all depending on your goals.My family has been in the Mount Vernon area for 20+ years now, so that's my farm area, while Anacortes is my place of work and hopefully live soon.

I know that might be a bit of a stretch but I have excellent credit and am willing to put skin in the game.

There are many ways to find motivated sellers - you have to think creatively...there's more than one way to skin a cat!
