I’d also ensure there’s a spot for them to state when their lease ends or is MTM.

Currently in NJ 20% of the purchase price must be paid on the spot at auction and then the remaining balance paid within 30 days.

If you want to account for those expected cost just put the $125 ($500 x 3 / 12)  in the "other expense" spot on the calculator. 

I've consulted his opinion a few times regarding MHP issues and such and I can say that his advice was spot on.

To be in a good spot as an electrician you need to get your master license.

@Mindi Rosser @Zach Schnoebelen Mindi is spot on.  

Plus Jake's comments above are spot on.I'm also new to BiggerPockets but I'm a 3rd generation investment property owner in Seattle. 

You can also look at the listing to see how many and what kind of parking spots are claimed there. 

Population growth, job opportunities, current business that are in the town and then businesses that aren't in the town but are in towns that have similar demographics and populations that also do well that could be potential places that would lease commercial spots if someone were to develop it.

BUT the same thing leads to good $ (relatively) for flips, as people pay stupid $ for sfh's in the best spots...
