Use the following in Excel and see if they help, =NPV (Net Present Value) put your down payment on the outside of the formula and make it NEGATIVE (cash flows go inside)...this will compare to another interest rate (i.e. stock market return compounded at an 8-10% rate)... if you are withdrawing this money consistently obviously this will be different, but both are considering that you are reinvesting and not taking the money and buying fancy Rolexes, cars, etc....

Obviously it is code to have the ability to escape both bedrooms in the event of fire, but could this be mitigated by a sprinkler system or is this effectively a 6 unit apartment building?

Can you see any negative to listing it on Zillow ourselves before we list with an agent?

But I'm wondering if they are as useful and applicable (i.e. the ability to edit) and if there are other more cost effective means to obtain said documents.

If I use the 50% rule for operating expenses and then just calculate a mortgage payment of 667K at 5% with no money down, the cashflow  would be negative at around $1700 per month, which certainly is no deal. 

Can anyone suggest effective platforms they use and are satisfied with (because the system provides accurate information)? 

Quick sidebar, if the same prospect receives 25 postcards from different sellers all saying the same thing, the message begins to lose effectiveness, and it might be time for the savvy marketer to move to something new. 

But here's why -The property (A) I am selling has big negative cashflow, which is pushing up my DTI and thus preventing me from doing a cashout refi on another bigger property (B).My mortgage broker has been working on the numbers, and one way he came up with is to deal with A and B at the same time.

Even short term would help, so you can get your feet wet and prove you can run the units effectively.

Yes in theory you can wholesale off the MLS but in today's competitive market it is not a very effective strategy.
