But how do I calculate that into the deal?

I’m genuinely curious how people analyze property without using the BP Calculators?

Everything comes in to meet codes using this calculator with specs below, except I don't know the above floors headroom yet, but I am confused by the total run of 202".

Also none of the calculations above include appreciation in value of the property, tax savings, or principal paydown on the loan. 

A promissory note would not be seen and calculated in your DTI.

How are you calculating break-even?

I've used the calculators on site to make sure it cash flows and it does double what owning a single unit would. 

Even worse, is people that start investing and never get this info (Which means risk they don't even know about, because they haven't calculated it), when they can- for free and pretty easily.Short version- there are 2 "team members" every new investor should loop in ASAP to be financial guides and help paint the financial road map of where you are and where you need to be- and what your financial expectations can realistically be for when you proceed. 1) A great, seasoned full time local mortgage broker.

There is dealcheck, biggerpockets calculator and they will give you the projections.

3) When using the calculator on BP, do you want 70% of the refinance loan to match the total cost put into it?
