I will just speak on the Sacramento market.
1. People can afford what they are buying. The bidding wars are funded by cash/equity rolled forward. Average equity in the area is north of 30% (per Black Knight).
2. We have not built a significant number of housing units since 2008. In those peak years we were building 18,000 units a year in Sacramento... since then we have built 4-8K while we are getting 20,000+ Bay Area transplants.
3. The bidding wars are pretty heated for dialed in houses that are intentionally under price... and that is what we focus on but the reality is that not every house is getting 40 offers and going for 100K over. In Sacramento there are 1051 houses that have been on the market for over 30 days as of this minute. There are under 300 active listings under 30 days.
4. I see investors that cannot cash flow at the current rents but they will cash flow easily at market rate rents. The rental market is Sacramento is extremely tight with a lot of upward pressure. The landlords that are cashing out are mostly selling to families (who pay more than investors on FHA loans with 3.5% down) so the existing rental stock can command large increases (outside of covid issues). Look on CL, FB market place and zillow... in any zip code there are 3-5 rentals that get snatched up in days. Many of the older long term landlords in the area have people in place paying 60% of less of market rate. I am selling a 4plex house that will get $1500/mo for a 1/1 when renovated but the current tenant is paying $550 because they have been there 16 years. There are deals all over the place that cash flow easily at current market rents. You have to do the work to turn them over but the numbers are solid.
