This led to me learning how much of my payments were interest and principle.So I had my spreadsheet, with it's one formula...then I wanted to adjust the down payment to see how that scaled my payment.

Im not sure if I have the formula correct.

Unless you develop a magic formula for your letters, you'll likely have a low response rate - maybe 5%.

The building has approx. 35K sq ft living space and 1.5 arces gross.The Town Tax Rate is $13.34 per $1000 of assessed value.Is there a formula, a way to calculate, a ballpark Tax Rate and/or FMV after rehab?

If I go and add cells myself, I need to re-write the formulas for everything to flow properly.  

So the formula should look like this (Purchase price-land value=substantial improvement amount).

@Brad Swearingen every municipality uses different formulas to calculate their building costs. 

Idk if it scares off builders or these areas combine with much higher demand but the stricter the controls the higher valued the sqft formula gets imo. 7% annually compounded is not going to be cheap rent in a matter of months. 2k a month turns into $2600 a month in 48 months with my head calculator. 

We all have our own formulas for what we think is a good investment in any given market market...

Depreciation is calculated with this formula below:Cost of the Building- Value of the Land = Building ValueBuilding Value / 27.5 = Yearly allowable depreciation deductionMy questions are:What or which documents will provide me the 1. cost of the building 2. the value of the land so I can calculate the formula?
