YES lots of competition in Big Bear over 6k properties listed and to self-manage and make money you have to be really, really good ... there is a reason why platforms have algorithms to show only 'top' homes.

So, I can renovate any property in the US to move in condition by doing a cosmetic upgrade for $XX depending on the size of the property.This is just step one to get to an offer stage...you'll need to bust *** in due diligence to confirm your assumptions...a great agent can be your best asset here...or your contractor network.Unfortunately, the real solution is a wildly complex algorithm that will only get you marginally better results...remember, acquire properties by going through phases...phase 1 is getting comfortable with an offer based on what you know after the first filter...entering due diligence is where the real work starts. 

It was nowhere near $12,0000 and the algorithm that performs this task was calculated in error.   

Before I try to do the math, does anyone know of a formula/algorithm to employ for the best strategy to payoff multiple amortized mortgages?

Also real estate agents seem to always the negotiate the best contracts and get the best price that online brokerages can’t always provide or a compute algorithm can’t negotiate

I would not put a lot of time into a computer algorithm generated value.  

That's one of the major problems with Zillow algorithms....they have never been inside the house so their Zesstimates are never accurate.

The CEO was heard to say "We are losing $1,143 on every deal but we'll make it up in volume" ;-)"Zillow Shares Fall After Forecasting Home-Flipping Losses"Zillow Group Inc. shares fell as much as 14% in after-market trading after the company forecast that its new home-flipping business would lose as much as$80 million in the third quarter before interest, taxes, depreciation and amortization.The company generated $249 million in second-quarter revenue from Zillow Offers, an algorithm-driven spin on home-flipping, and received requests from 70,000 consumers who wanted to sell their homes to Zillow over the internet.

I do think bad data is better than no data, with regards to the Zestimate...My 'give them the benefit of the doubt' in their algorithm is that perhaps us folks that are interested enough to actually click on the 'Edit Facts' button (us) do correlate to being relevant to adjusting value - vs those that don't. 

Still I question if the algorithms can get the price right.
