Mathematically they could do 10+ projects but we settled on 8.

My day job involves identifying fraudulent documents, so it helps tremendously, and most fakes have spelling, punctuation or mathematical issues, or are just badly done overall, but there are situations where I am in doubt and would love a 2nd opinion.

That is how you know if something is a good deal or not... it’s whether it matches your strategy to achieve your goalA rental property is very simply mathematical equation.

I am not saying don't buy turnkey but if one wants to compare to the averages on returns to LA, SF or San Diego historically there is a very clear mathematical answer.

For example, if you have a background managing properties or working for a large financial consulting firm or studied migration patterns with a PHD in mathematics.

But also you can more easily pull that money back out in the form of a HELOC much easier from a primary home compared to the rental.So in the end do you want peace of mind or mathematical optimization (which some would argue is leverage even more!)

I know they installed rear unit completely new roof in 2017, so the roof in front unit is the main concern for me that will need to be replacement in future, what I am thinking is that if I back out, I lose 11k, which the flat roof in front unit will cost less than 11k, I think you got great point here and I probably will stick with inspection in future, but mathematically speaking I was leaning towards account for roof replacement in future ?

So it is entirely possible that you could be required  to accept somebody with ZERO verifiable cash income,  for example being required to accept somebody who mathematically won't be able to pay all the rent  (say they have $1900 sec 8 voucher on $2000 rent with 3x income ratio,  and $300/mo SNAP benefit, and zero verifiable cash income)  If you get that situation,  contact an attorney before doing anything else)FWIW if you have reasonably strict criteria on prior landlord reference,  credit,  etc. 

They're directly/mathematically related - reciprocals.   

@Danny McGreevyPutting down a smaller amount and investing providing you have some hold time is mathematically better.
