You may want to use your local GIS map for tax information which will typically give you current owner address (important for direct mail), bed and bath count, square footage, lot size, year built, last sale date, last sale amount, current year appraised value, etc.

Usually 15 years is not figured, People usually get 30 year loans, but depending on the size of the multi family most of the times they are commercial loans and are usually 20 years.

This beam could be a difficult item to replace due to size and access.

If the zoning has changed (setbacks, density, etc) then you will be able to put back the same size structure that currently sits there because it's grandfathered in.

The quality of your deal and the temperature of the marketplace will dictate the size of your fee.If you are double-closing, your buyer will pay a higher price than you are paying your seller.

@Kiersten VanceHello,I am part of a real estate group doing an infill subdivision offering three different sizes/price points of duplexes.  

There is no one size fits all plan...

This type of window requires little or no alteration to the exterior and interior components, providing it is sized correctly.

You will significantly reduce the size of your buyer pool if you don't.  

I apologize I may seem absolutely off the charts bonkers on this.
