We tried to send them the comps we were seeing that more accurately reflected the value etc... 

If you used your net income (or more accurately your tenants) to pay down the mortgage to $0 you till have a gain of $100K even though the cash you receive is very different.  

Surprisingly, the addresses and relative information is accurate for a free tool.

The problem is to make an accurate analysis and ultimately an accurate presentation to the lender I have to first get access to the property.

However each inquiry is only a 5 point hit if that.Submit it to lenders with instructions to base the pricing off the submitted current  Tri merge bureau and not pull a new one until you have formally applied.This allows them to accurately price their product and generate the estimates.

I am currently analyzing deals, however, I cannot accurately estimate the cost of repairs/rehab since I do not have any hands on experience.

As for the comps, make sure that they're within 1/2 to 1 mile at most of the subject property for accurate comparison.

I think the program is okay for a part of a portfolio, but don't limit yourself because "getting paid" every month is only half of the story...Posts about getting shot are not accurate in my experience. 

I liked the way mint pulled Zillow’s Zestimate (May not be the most accurate, but at least it tracks it) and kbb’s car values to update the value of homes and cars.  

I'm considering getting my license solely so that I can more accurately comp out houses and make better offers and maybe be able to view houses on the MLS on my own schedule.
