The main point of my question is should I expect to discount my sale price on synthetic stucco if I am pricing against other homes of brick or hardyplank siding so that I overcome the synthetic stucco concerns.

Inside the building look for the tell-tale weeping bubbles on the pipes.If you are going to be digging to the curb and replacing supply, the incremental for replacing waste will be small compared to returning in 3-5 (maybe 10 if you fortunate) years to dig again.Sometimes, if the pipe to the curb is not too bad, you can insert a sleeve through it ... basically put a synthetic pipe inside the cast iron.

I dispute your characterization of the properties as highly illiquid: while true liquidation is difficult in a downturn, there are products that offer synthetic liquidity, such as cash-out refinancing and HELOCs, as well as collateralized loans against the portfolio, once it reaches a certain size.

Make sure you have REAL stucco versus synthetic ( EFIS ).

Even if they add kitchens and laundry rooms, it'll still be too synthetic.....

However, I will say, any market may be synthetically inflated/deflated due to propaganda, politics, or gouging.

In my case I was going to create a synthetic first and second note, from the single note obligation - giving the first holder (you) priority but further delineating the process of how the subordinate partner would have the right to foreclose, fix and resell and both partners share in the new profit, or simply abandon their ownership which leaves the first holder with more equity.
