It's just an accident waiting to happen IMO.Why take a risk?

@Patrick Roberts to your point about risk tolerance, I think that pretty well describes me.

@Robert OkChoosing between single-family homes (SFH) and multifamily properties depends on your budget, risk tolerance, and long-term goals.

The key to reducing the risk of non-payment and property damage is having a structured screening process that looks beyond just a credit score.

Look up the default risk by credit score, this information is readily available online. 

Originally, I was going to invest OOS but the risks of that concern me.

Your suggestion of a Vanguard money market account is a good option, but since SIPC coverage on brokerage accounts only protects against broker failure (not investment losses), the Vanguard Cash Plus Account with FDIC insurance up to $2.5M is a safer alternative.Other low-risk, high-liquidity options to consider:Treasury Bills (T-Bills) – Virtually risk-free, exempt from state tax, and currently yielding ~5%.

Understand the Insurance GapsResidential insurance covers owner-occupied homes but often excludes tenant-related risks (e.g., rental liability, tenant damage).Landlord insurance covers rental properties but assumes the owner doesn’t live there.Your need: Hybrid coverage for a property that’s both your primary residence and a rental.2.

While STRs often have quicker turnover, screening can help reduce issues with property damage, chargebacks, or problematic guests.If you're concerned about high-risk guests, you may want to use a third-party screening service that pulls comprehensive reports, including identity verification and past rental behavior.

Your goal is to make a financial return commensurate with the risks associated.
