There is a sense of accomplishment in remodeling a kitchen or changing your own oil that you can never get by pressing the send button on an important email or crafting a really nice excel spreadsheet.

Jobs consisting of oil mangement, engeneering, computer it, pilots, small business owners.  

My ads always have the rent, utilities the tenants pay, amenities, appliances, schools, security deposit, length of lease, type of heat (gas, electric, oil) central air, fireplaces, garages, off street parking, who cuts the lawn and shovels snow (hint its not me), credit and criminal checks, and neighborhood highlights like busline, and police station in the next block.. 

@Denise Cook, If you're simply looking to get financing for a duplex in Philly, you would not need to inquire about commercial loans because it is under 5 units.

In NY the process is:Write offerSign contract with 5-10% deposit (This is where you have the deal locked up.)Due diligence, appraisal, inspection (I've never seen an investor supply financial statements honestly, usually just tax bills, rent rolls, oil/nat. gas bills and insurance.)Assuming everything checks out, you're clear to close.

Maybe the heat goes out and they need to push the button because they ran out of oil.  

My business partner and I had invested in oil and gas in North Dakota during the last oil boom, in 2010, and could never find housing when we went there.  

@John Cook The expenses should be proportion to rents.

The Nest seemed like a perfect compromise for keeping Mom comfortable and with a sense of control while not cooking the rest of us.

Man camps for oil field workers are nothing new around here.
