Due to item 1, adding an ADU can require years to start achieving any return (once the accumulated cash flow recovers the initial negative position).4) Adding an ADU is a slow process.

I also find that depending on the tenant, my one Airbnb property has less wear and tear because it's constantly cleaned and maintained versus my other rentals where the families living there settle in and accumulate stuff - which makes it hard to deep clean regularly (to my liking) as well as just the constant daily wear and tear from kids etc. 

I've been doing a deep dive looking at cash on cash return for various down payments and expenses on properties with a mortgage.

It is a slow time in the market overall with the holidays this month and next.

@Lolo Druff Real Estate Investing is not like Trading Stocks or Crytocurrency.Real Estate Investing requires some deep thought and research from you as an Investor.Having 400k to deploy to multiple duplexes is a great start but you have some questions to ask and answer yourself.

We didn't anticipate the housing market slowing when it did in August and now we are holding a flip that for all accounts should sell.

Fast solutions have slow problems.

If you have 60k equity and 10k cash, slow down and remember this - you need 15k for reserves for a new property and you should always only use half of your equity which would leave you with 15k for downpayment and 10k cash for renovation.

It’s not wise to invest blindly trusting the operator reputation alone, without deep diving into many syndications.

US population growth slows and fewer new households form, which is probably not great for RE investors; and 2. the Social Security trust fund runs out.
