I find that depending on the market $300-500/mo are fairly normal and if compared to what you would pay with a single family home on some utilities, maintenance, and management, it's a good deal.

IF my numbers are truely "too low" I just looking gain confidence in how I am analyzing properties and estimating repairs.  1710 10TH AVE N, 37208: https://docs.google.com/spreadsheets/d/1B0CoSbGxQFbRBVzXBERw...6121 Southampton Dr 38119: https://docs.google.com/spreadsheets/d/1a3WBEcgv2SMggu5P2HrK...2014 Salem Mason Dr, 27208: https://docs.google.com/spreadsheets/d/1Jzr5TN9PYhuiFuD2THLb...Spoke with a seller yesterday, before I go with these numbers I thought it best to ask for some guidance. 

Most of those old houses with the upstairs ceiling rooms are just about 7 ft in the middle of the room but they go down to as low as 3 ft.

*Look for properties where you can gain immediate equity by buying at a low price.

.- PM is contractually obligated to perform annual maintenance/inspection to keep property in top shape. - PM provides a cash based accounting report every month, for every unit under management, that clearly labels all rent, all expenses, including management fees, and the net directly ties to the amount of money deposited into my bank account.- PM is a licensed handyman, or has them on staff, and takes care of most unit turn work at a reasonable rate. - PM has no breakup/termination fee- PM does not take project management fees, except on large or complicated CapEx projects exceeding $5,000. 

It is pretty low risk from my viewpoint.Then, after you've sold the first property, you could buy another home that needs to be fixed up, live in it as your primary residence, rehab it, and sell it again after living in it for 2 years as your primary residence out of the last 5 years.

In general, I would say Kitchen, Bathrooms and any deferred maintenance should be your focused items. 

-------------------------------------------------------------------------------------------------------Recommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.Property Class will typically dictate the Class of tenant you get, which greatly IMPACTS rental income stability and property maintenance/damage by tenants.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a property in Class D area to Class A standards, what quality of tenant will you get?

Quote from @Michael Daniel: Purchase price 70k currently pulling 900 rent ARV 110 - 140k, rehab about 25k @Michael Daniel That rent sounds too low for that ARV.

When revenue is low in the first couple of year, so is the interest payment.
