However the MLS is retail so don't be surprised if they don't find what you are looking for.

Every person that calls me wants retail prices for their house, or has basically trash houses that I wouldn't pay a dollar for...

That is, find a retail buyer that can purchase the property.

They might have a great algorithm, but it doesn't take into consideration the elementary school abutting the backyard, the freeway a block away, an overbuilt or underbuilt house, that in some neighborhoods a pool actually is a negative value, a garage converted into a bed & bath, a one car garage in an area of two car garages, etc. etc.

If not significant, buy-rehab-sell retail.  

@Jay Hinrichs And it doesn't kill value, because if I sell I'm going to be selling at a retail price. 

There's so little inventory regular retail buyers are buying houses that need work, because it's all they can find. 

Now when you market the property you have pictures, video and a written description: how many beds, baths, sft, taxes and liens if any.

Might be ok for a rental, but not retail.

So at the end of the day, i still need to budget for roughly 10% of the sales price in closing costs regardless of it's a retail flip or wholetail deal.
