This will free up extra capital to pay off your loans faster or reinvest.

Yonkers appreciate me faster than Stamford.

Sometime you have to learn the hard way but also if this is a first investment I would recommend it being within driving distance to where you are living so that you can learn the business and meet with the contractors to scale faster.

I would try airbnb personally, they can make a lot of money (get you're 60k back faster), but has the potential for a little more headaches from what I've been told.  

We have a signed lease within two weeks, sometimes faster and three at the most.

On a small scale like a duplex it's seldom less expensive but should always be faster leading to faster occupancy, less general conditions and less financing costs. 

Landlords who want to cater to a graying tenant base might want to keep these ideas in mind if they want to make their rental units senior friendly.The cost of any health care plan is high and premiums increase each year much faster than the rate of inflation.

Unless you're already bankrolled, you're really not in a position to do this yet.

I thought it would be less expensive and faster.

I suspect this is in error if you are thinking about CCR (cash on equity, really) - cash-on-equity return generally DECREASES every year, as your equity increases faster than your rents (your net annual cash profit divided by the equity in the property - calculate this, its likely very small if what you say is correct).
