So I estimate I can get these additional seven properties within the next 12 to 18 months if things with financing go well.

(Estimated rent minus all expenses).

I am estimating cost saving since I did not get quotes getting these written.

How good are your estimates.  

I’ve been learning how to deal with seller objections, trying different marketing methods, setting appointments, estimating repairs and formulating an offer, and learning more about the indianapolis market.

In addition to the $28,000 there is a $300 wholesaler fee and then closing costs which I estimate to be no more than $2,000.

You need to learn how to estimate a rehab yourself. 

Or are we suppose to estimate by sq ft?

I am getting a 7.5-8% cap rate using conservative estimates. 3.8% interest rate.

I realize taxes are paid yearly, and any other costs on the property (repairs, improvements, property manager, travel costs, etc.) will reduce the income I am paying taxes on, but for now I am just trying to get a general estimate of the monthly breakdown.Please point me to some resources that can help me understand how to best understand and handle taxes!
