And you don’t mention whether the fuel source is electric or gas or oil.And all of the above assumed a central heating system; it’s quite possible you have electric baseboards that could lead to other questions ...

@Hayley Young Stay picking up those free magazines that are in the front of gas stations, Drugs stores...etc.

The installer is in PA and violated local code, the national gas code, and manufactures requirements with this install and did so in a completely unsafe manner.So now I have two options. install a new heating system or build a chimney. both range from 3500-5k,  but the initial reason for this post is does anyone think I have a leg to stand on with fannie mae and try to have them rectify this? 

Here are the inputs:Purchase Price: $400-450K per propertyDownpayment + Closing Costs: $90-100K per propertyMortgage Payment: $2,000 - $2,200/month assuming $2K/year taxes and $1.5K/year insuranceTotal Monthly Rental Income renting out all the rooms (6 bedrooms x $700 rent per room on avg): $4,200Total Monthly Rental Income renting out all the top rooms (3 x 700) and renting the bottom unit to a family ($1,700): $3,800Total Net Rental Income Before Utilities/Maintenance/Reserves/Capex:  Low: $1,600, High: $2,000Utilities: ~$400 assuming that you pay for everything, internet, heat, electric, gas, water, storm drainageMaintenance/Reserves/Capex: $400 to have enough to cover any items that could need repair, maintenance, etc and accounting for age of house and more wear and tear Total Net Cash Flow Per Month: Low: $800/month High: $1,200/month, Middle: $1,000/monthAlso, I didn't include you adding any extra rental income for for adding utilities to rent/garage spots rent/etc, so these cash flow numbers are very conservative but realistic. 

I used to work in the space program before going into oil and gas.

REAL ESTATE is an investment, just like precious metals, stocks, royalties, equipment, oil, gas, etc I assume you work for a company that only sells stocks and bonds thus the tunnel vision-not your fault.

Looks really high, compared to the purchase price.What's the charge for "gas?"

What kind of easement is it, i.e. electrical, access, gas, etc...? 

@Raj G. As

What is the best way to reach out to potential retail/gas/self storage flag ship stores?
