Most are listed out as "estimated", i guess because the property is that new.

Don’t under estimate capital expenditures, vacancy rate and rwmo costs.

I calmed down after hearing some more details and thinking it through.   

And to your point, if you find someone who can do quality finish/detail work do whatever it takes to keep that person on your team. 

Would you like to jump on a call and discuss details?

I am afraid that I will buy it and stay vacant because is so big (It will rent at about $30,000 per year and renter is responsible of NNN,or at least is what the realtor estimated).

I estimate it would take 1-2M of invested money to hit my cash flow goals.

Can i then estimate the cash flow of  a property before i buy it, by simply estimate the monthly income per door and subtract the expenses? 

@Andrew Wilson a couple of things here:If you are using a Fannie/Freddie loan (those are the ones with the lowest rates on a 30 year fixed) then the cash out limit on a 2-4 unit property is 70%If you are seeking cash out in the first 6 months, Fannie/Freddie loans will have some pretty detailed restrictions. 

If the owner doesn't care enough to find keys and grant access, you might do your best to estimate rehab costs and explain that when you make an offer (assuming a low offer).
