Here are the details on the property:Beds 4 Bed Baths 3 Full, 1 Half Bath House Size 4,530 Sq Ft Lot Size 1.3 Acres Year Built 2000 The property is not listed on the MLS.

I looked at a property, rented section 8, that had a 3 bed at $1,250.

Typing this on my right before bed did not help my writing skills ;)

@Chris Duzan A buddy has 130 beds brings in 71K mo after expenses 50K.

It's a 3 bed/2 bath with a large loft (1900+ sq ft).

Hi All - I have a 1 bedroom house and the roof/ceiling is leaking into the bedroom (over the bed). 

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.

I can't imagine what you consider to be D stuff! 

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