We do mobile home parks so we typically are not looking for one person to do a general inspection but we hire a plumber to come out check water/sewer/gas lines for a professional opinion , same with electric , or if there is roads that look kind of questionable, we will ask a paving /concrete contractor to look at it.  

I changed a water heater, huge leak in one of the units, electrical issues, and I even had to dig a 3 foot hole under the house and personally fix a pipe.

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.

Mold is caused by water.. you have to stop the cause of the water which is usually pretty easy to do if it's a leaking pipe or a busted roof.

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.

I have a building right now that's leaking water into people's unit but the owners won't do anything about it because they don't want to spend the money.
