But as Johann notes, it's extremely important to make sure your assumptions are accurate, or as accurate as they can be with such things.

The foregoing general rules and the following discussion of factual situations may help licensees accurately draw this line.

But sites like: Zillow, Redfin, etc. are not very accurate source to derive comps.

In order to ensure your cost estimations are accurate I would get actual bids during your inspection period. 

.- Online valuation tools do not give an accurate ARV, we consult a realtor.- Property values are going up, but we cant fix a property and hold it until prices go up...The list is much longer, I am sure many our BP readers can add to it, but these are the major hitters.

Is that accurate information?

It is pretty accurate and up to date.

Find the taxes due on the local assessor's site for an accurate number and call an insurance agent for an exact quote, it's free.

I do find that Rentometer.com is fairly accurate here too.

Does this sound accurate or should I be looking for another mortgage officer?
