I’m thinking 3 bed 2 bath (or something that could be converted to this) somewhere in the price range of 125k to 175k around 1500 sf.

Worked out of Atlanta for a couple years before quitting and moving to Fort Collins, CO to live the “front range ski bum” life.

I originally thought about putting a gravel parking area along the front/side of unit D back towards A as there is a curb cut for a drive and 2 units are lower level and the entrance is on that side of the building (cost would be about $5k range for it but would be more of a ). 

I suspect, given what you described of the situation, that someone used a stainless-steel quick-connect gas hose kit to put in your range and didn't use pipe dope, or thread sealant, in the installation.

@Gary ParilisEquity Trust is a custodian, and does not offer or support the checkbook IRA LLC model.There are a variety of pricing models in the custodial range of services, from asset based to flat fee-per-transaction and a variety of hybrids. 

Based on the 2% rule/guideline, the rent should be in the $3000-$3500 range which doesn't seem feasible.

Personally, I don't recommend anything below a C class which pricing will start in the mid $70K range and rents of at least $750-$800 on a 3Br.

In Indianapolis, this will be in the mid $70K range and mid $80K range in Kansas City.

Get a sense of the range of cost for each specialty your project will need.

MHP Parks are trading anywhere between a 10% - 13% cap rate so make sure you crunch the numbers and that you are in that range.
