I think there's a lot of money to be earned by turning a slow, tense process into a fast, lower stress process.
I think there are probably thousands of other industries/segments where an aggregate hundreds of millions or billions of dollars are spent annually and where people would spend 1 to 2.5% extra if friction were noticeably reduced. That used to be flights, hotels, and cabs that have been made easier in the last 2 decades.
While it's definitely possible to improve the experience around that, I don't think it really qualifies as market making. Specifially, look at wikipedia's definition:
>A market maker or liquidity provider is a company or an individual that quotes both a buy and a sell price in a tradable asset held in inventory, hoping to make a profit on the bid–ask spread, or turn.
You can't really hold "renovations to be done" as an "asset in inventory". It'll be something like uber, ie. a marketplace, not a market maker.
And all three have severe government monopoly powers and competition killing regulations.
but used cars seem to do fine, even though they can be similarly damaged?

Repair costs are also better known and less daunting.
I don't think my mortgage lender has ever inquired about the age of the roof on the purchase or during any refinances. For my first house, I bought it with a roof that needed work, had some small leaks, and was well beyond its design life. I got a mortgage without the bank bringing that issue up (albeit in 1996).
Home inspectors look at these things and buyers might choose to walk away based on the inspection report (which the bank never saw on either of my purchases).
It probably helps that the entire house could just disappear and the price for the lot would only change 10% or so.
And property taxes. And security. I do not know who ran the numbers on this program, but anyone with even a little bit of real estate experience was wondering what the hell they were doing. Blackstone has been around and killing it in real estate for 20+ years, and you would figure something obvious like what Zillow was planning to do would be on their radar if it made sense.
Zillow SAID they wanted to be a market-maker, but they ACTED more like a flipper or investor, expecting to make a profit on the houses themselves, not just on the spread. When they started making above-market offers on homes they pretty much left any pretense of market-making behind: at that point, you need to either sell at a loss or hold inventory and go (a little) long on your investment. Zillow realized they didn't want to hold inventory.
It doesn't help that houses aren't nearly as liquid or fungible as stocks: buying a house, prepping it for sale, accepting and offer, and closing takes months, and all that time can eat into your spread. Zillow would probably always have ended up in a situation where they were more concerned with the sale price 2-4 months down the line rather than their spread.
I think they do exactly what you say, give a quick cheap offer, then do some fixing and sell the normal way for a profit.
Basically, if you can convince someone to sell for x% less than the real price today, you can make x% - some costs. Of course this has huge variability, but the company I noticed do it in one market they probably know extremely well so they can make good bets.
In a red hot market, I opted to let the market decide the price and terms.
The exception being that there is a lot of middleman involved, loan agents and purchase agents. So cutting out these should save at least 5%.
