We bought land with an ocean view, built and furnished for a total investment of about US$300,000. 

At the moment I have four rentals, all SFHs, and bought starting in 2013.

It has appreciated since we bought it but it's not enough at the moment.

Questions like: How long do you have to store his stuff?  

High inflation means that people will be looking for products that can store their wealth (aka "liquidity"), such as gold, cryptocurrency, or real estate.So why buy real estate during inflation?

If I sell I would be able to get what I bought it for.

If you bought something more standard in Ohio you could do MTR there and have less turnover and less furnishing expenses.

I started my real estate journey 2 years ago and bought my first duplex fully rented.

I was a project manager and engineer first, and bought a house hack years before I was licensed.  

And it required a lot of time and effort on my part whereas the syndication stuff is purely passive.But there's no way anybody can tell me that sfh rentals - if they are bought right at 70% ltv or better - are not going to return way more than anything else on the planet when you factor in how little money you actually have to put into them to begin with and then you let appreciation and principal paydown and rental profits pile up.
