This could avoid vacancies and the cost of placing new tenants. 

Other than oblivious items like appreciation, medium house price, vacancy rates, expected population growth, etc...What are other things you look for, compare and analyze when looking at new markets and states to invest into??

I would want to know what the turn-around time is for maintenance requests and vacancies.

That does not calculate in vacancy rates and capex and repairs....so maybe you need more than 14 properties.   

Proximity to Disney, Universal, and SeaWorld help a lot with minimizing vacancy.

I used the following to calculate expenses: 5% vacancy, 1.16% property tax, 5% of effective gross income for repairs/maintenance , 10% property management, abt $1,100/yr gardening & utilities and $1000/year  for insurance).

Since this migration has begun, rent prices and home prices are beginning to feel it's effect.I helped a client purchase a duplex in Boise last year, and she is already cash flowing with 0 vacancy.

You want to use the more conservative rent number, plug all this in to the BP calculator and you will more than likely not pencil out when you put in a conservative 10% for property management, $ for reserves for repairs, maintenance, vacancy, etc.

otherwise let me be the first to say, RUN. do not buy this. ok with that out of the way, a few things you can adjust to give you a more realistic picture in the calculator. no matter what you'll always be spending some money on repairs when you first get into a place, so off the bat i would put a grand or two for estimated repairs. i run my vacancy numbers at 8% as this is just about a month. your capex should be lower, unless this place has some really big ticket items waiting to die. same with repairs. also the insurance numbers and property tax number both seem very high, is this the real numbers or just place holders?
