Assuming gas is $100 and electric is $50 a month.

Any option for gas in your area?  

You add transactions with my suppliers, about 100 Purchase Orders a month (excluding HD), you add my gas, my employee's gas which I give a weekly budget, add any meal refunds for legit claims.

Paid $96k for a 2 Bedroom, 1 bath HUD home in downtown Windsor, CO in Nov. 20133.5% down, FHA with escrow account - we had 30 days to paint exterior, get water, gas, electric turned on.

Especially the days when you discover that big capex like a roof being blow off (happened 2 years ago), some tweakers climbed up on the roof and gutted the A/C (did two of those in the last 12 months), an evap cooler leaked for so long that the drywall on the ceiling of the kids bedroom caved in (last year), the hot water heater blew a hose and a major leak went unnoticed for 10 hours flooding the hall, kitchen and living room (dealing with that now), the tenant smelled gas outside, the gas company came and shut off the gas because the underground pipe is corroded AND also discovered that the water heater is not venting properly so it got red tagged (just dealt with that last month) or the time the tenant "invited" a homeless guy over, he moved in, then called his other homeless buddy up and he parked his crappy RV with his entire family living in it in the driveway.

I am a Master Plumber and a gas and HVAC technician.

WSG is $100 gas and electric is around $100 as well.

@Jen TeskeI don't know the area so I can't speak about the market you're in, but just by looking at the #s, you're missing a few things: Water, Sewer, Heat, Electric, Gas, Trash, Lawn/Snow removal, Cap Ex, Property Management (even if you're self managing, this needs to be factored in if you want to scale), and although you did include vacancy, if a real vacancy were to occur on a SF you'd have a 100% vacancy, making it negative cashflow since you'd have to cover all the expenses, not knowing when it'll be filled again. 

@Jim AdrianI can get estimates from the modular home manufacturer.I'm looking for some idea what to expect "resurrecting" a subdivision that was never completed: complications with the city, dealing with the utilities - electric, gas, telecom, etc., merging new homes with the existing HOA (if any), ...
