Insurance was calculated using this equation $6/$1,000 of ARV + $500 if unoccupied.

Maybe more percentage of unknown into my equation would help this out.

Yes your interest rate will be higher, but your balance is also a factor in the payment equation. 350K at 3.75% vs 100K at 14% is roughly the same interest payment. 

I am not sure the Rehab budget equates to the big jump in Value you are proposing.  

To equate the difference in understanding one over the other to the difficulty level of understanding quantum physics is ridiculous.

Your property exceeds my criteria.If we estimate operating expenses at 50% of rent then we have $9,450 net operating income  At a 10% cap rate that would equate to a value of $94,500. 

I am all for finding the best deal I can for my clients and myself but reality has to be part of the equation.

They equate it to a mobile home park.

I guess that I'm equating it to a Realtor that takes an overpriced property just for the listing.

For that Amortization Table though, Include a Column for Additional Principal Payments, and make the Running Balance Column Equation: Prior Balance-Principal Payment-Additional Principal Payments = New Balance.
