Best bet is to talk to some site work contractors in your area as those costs have risen dramatically lately.A lot depends on the land itself in terms of topography, timber, rock etc.

I'm starting to see a couple of cancellations at my STRs, though it hasn't been dramatic (yet).  

Likely to Revise 2020 Forecast Downward, But Not Dramatically: The situation remains fluid, and conditions could deteriorate beyond what is currently envisioned depending on the severity and duration of the outbreak, but if current economic forecasts of modest declines in GDP growth are realized, the effects of lower rates should help to offset the effects of a slower economy and increased economic uncertainty such that California would still achieve a modest improvement in both home sales and prices this year.

For example, depending on which “expert” you listen to, the stock market is: about to crash, will rise dramatically, will change little, etc.

If they can start reporting the facts (get a scientist to do it who is good with the media as they are less dramatic than the news reporters and better at sticking to the facts) and the politicians act on facts (not concerns about being sued), it would help a lot and solve most of the problems (well not create a cure for the virus). 

I wouldn't be surprised if the market bottoms out at about 15,000 on the DJIA, and after this is all over, will rise dramatically again. 

SFR rental demand has increased dramatically as people was to stay away from communal living situations.
