The SFH is in my neighborhood where I live so I know that area very well, so I feel safer investing in something near my residence but at the same time that 4 unit will produce more income so I'm torn about what to do.....

If it puts their client in a bad light they could get in trouble for telling you that.

I am looking to buy my first deal in the near future and this is the part of the calculator that I have the most trouble with.

They take into account of your credit score and the income produced by the rental to be able to support the loan.

This would just use the income produced from the rental as the income to support the new mortgage.

Yes, you will have a mortgage on 16 properties but the income will cover all your expenses and still produce some cash flow.

The appraiser had trouble finding comps so he used comps further away and up to two years old.

Running the generator on the hydrogen thus produced and replacing the Natural Gas used in the home or business just makes sense.

If they find you are coming up with reasonable numbers, they are more likely going to trust your deals in the future.A blanket cost per square foot is not going to produce good results. 

Good to hear that your cabin is still producing well without internet.
