@James Woodrich - I agree with the $100/door as we use it a minimum when napkin testing a potential buy & hold rental. 

My quick, back of the napkin math, says that I'll generate at least as much income from that 1 connection this year as I paid in tuition to Xavier.  

(A) A landlord who is a party to a rental agreement shall do all of the following:(1) Comply with the requirements of all applicable building, housing, health, and safety codes that materially affect health and safety;(2) Make all repairs and do whatever is reasonably necessary to put and keep the premises in a fit and habitable condition;(3) Keep all common areas of the premises in a safe and sanitary condition;(4) Maintain in good and safe working order and condition all electrical, plumbing, sanitary, heating, ventilating, and air conditioning fixtures and appliances, and elevators, supplied or required to be supplied by the landlord;(5) When the landlord is a party to any rental agreements that cover four or more dwelling units in the same structure, provide and maintain appropriate receptacles for the removal of ashes, garbage, rubbish, and other waste incidental to the occupancy of a dwelling unit, and arrange for their removal;(6) Supply running water, reasonable amounts of hot water, and reasonable heat at all times, except where the building that includes the dwelling unit is not required by law to be equipped for that purpose, or the dwelling unit is so constructed that heat or hot water is generated by an installation within the exclusive control of the tenant and supplied by a direct public utility connection;(7) Not abuse the right of access conferred by division (B) of section 5321.05 of the Revised Code;(8) Except in the case of emergency or if it is impracticable to do so, give the tenant reasonable notice of the landlord's intent to enter and enter only at reasonable times.

Anton  part of it is keeping up with the Jone's  if abc turn key presents their product with blue sky it makes the others compare apples to apples.easy napkin math is simply 40 to 50% of rent will go to long term ownership. you may do better you may do worse but if you use 45% for instance it would give you a pretty good idea how it will perform over the long haul. this works good for 800 to 1200 dollar rents.. if your buying D class with 600 rents this number is probably WAY lowthis type of thing is soup de Jour with commerical brokers selling Multi family.. they only present the best case scenario its up to the buyer to do their own reality check

Also I have regular check ups from the health department to ensure the hotel is in sanitary condition and able to rent rooms.

For blind/napkin calculations, I use 12-15% (rents are lower in my area than many, and a roof costs about the same.)Being as accurate as possible is better, and there are some great strategies here for how to do that based on all the factors. 

Contractor does it on a napkin in his truck.....or he says he doesn’t need prints, he’s been doing construction for 30 years.

I use my own cash-flow projections (similar to Ali's cash-flow napkin and others) and what they were offering fell line with what I was seeking.The "kind of neighborhood" question is always tough.

Generally considered a quick napkin test to determine if the asset qualifies for further review and analysis.

Pardon my ignorance, but in reviewing some income statements for investments I'm trying to make sense of some napkin math concerning Net Income and Distributions.
