The layout looks like it might be a bit odd with the large addition on the rear. 

This way I can list it for families, but that's a bit of a weird layout and the quote is $14k to do it.  

Rick H. mentioned, reliance on calculators hinders your ability to think instinctively , objectively, you won't be able to adapt variables in reality that come to play in the analysis of real estate, or law, or economics, or finance or accounting or any other professional endeavor that requires intuition, abstract thinking or layers of relevance of variables in circumstances or situations. 

Sometimes on their site they also have a prototype layout for a freestanding building and what size acreage needed along with target demographics for median income, daily traffic counts, etc.STNL means single tenant freestanding buildings and MTNL would be multi tenant of more than one freestanding building connected together.

Again I'm working on an identical layout house across the street, that just appraised at $105,000. 

By all means, give back, use your intuition about a tenant, and the first time the property is wrecked and you have a $3-5k bill to put the house back together again, you'll realize that giving back is not a good way to go.Been there, done that.It all comes back to screening.

I know many times with a do-it-all product, it'll get you going but may have short comings in certain particular areas when getting more advanced (example: flexibility of website lay out/ videos/ linking to social media and blogs?)

The layout is great.

Someone else might consider that number great if they are in a tight market and all they do is lay out some money and watch everyone else scurry about. 

Your intuition tells you a lot.
