Mathematically there is no stretch of the imagination that makes sense here.

Even if you didn't do yearly incremental increases but did one lump increase X years down the road, most tenants will not like that even though mathematically they are getting a better deal. 

NOTE: I assure you that the Mason Rule is not named after anyone in particular, it was just coincidentally mathematically derived while in a Scottish Rite Masonic Temple, hence the name.

However I can tell you the vast majority of Americans are mathematically illiterate, so when you start talking numbers to most people you might as well be speaking Hungarian.

Versus in higher appreciation markets I would rate it as forced appreciation (your property does excellent), instant equity (your property does excellent), expected property appreciation (you believe your property seems likely to have good appreciation and I am assuming have done your homework), expected rent appreciation (you believe your property seems likely to have good rent appreciation) and finally initial cash flow (your property does OK but there are many locations in the country that do better).It is not arguable (as in mathematically it can be proven) that historically financed buy n hold in appreciating markets return better ROI than low appreciation markets that provide far better initial cash flow.I do recommend that you do the full calculation of expected cash flow taking into account mortgage payment, taxes, and insurance (PITI), vacancy, maintenance, and cap expense. 

I want to learn the logistics and mathematics behind purchasing multi family homes just so I make sure I am profitable.

Amanda, the housing market in Central KY is quite hot right now (as you already know) so it is going to be  difficult to find good mathematically feasible deals from searching the listing sites and getting MLS links.This is where your networking and creativity skills will have to shine to get the property you want in the area.

It's almost mathematically impossible to cover your monthly expenses with $1,800 gross and $900 rent.

Mathematically the federal government must run a deficit at least equivalent to the trade deficit in order for the private sector to achieve sustainable growth.

Well the mathematical breakdown was really helpful!
