I am curious how the city might go about regulating this since you cannot nail down the exact address of the properties by simply surfing the website.

I think @Jonathan Twombly hit most of the nail on the head.

@Adam PYou nailed it.  

If you screw up and do something unethical or just plain illegal even for your own account your broker gets nailed as well.  

Hi Nail, I appreciate your input.  

Id be in the wrong business and I would've nailed that billion dollar powerball. 

If you're going to immediately put all 30k into a down payment on another house, then a refi makes more sense because you are instantly tying it all up and you won't need the flexibility - so enjoy the lower rate.You may get nailed on a refi if you are not at or near the end of your mortgage term.Personally, I used a HELOC to buy my rental property and I have learned more since.

I generally give an opinion of what I think the price is, a possible range, how long I think it will take to sell etc. those sorts of things...and much of my opinions can not necessarily be nailed down to data that is hard and fast like in a CMA, but rather from the experience of being in the marketplace on a daily basis.

There's an old saying: "when all you have is a hammer, everything looks like a nail".

I think @James Wise hit the nail on the head!
