In my case, I have residential rentals in one LLC, commercial properties in another, self storage in a third, and my real estate company operates in a fourth.

Though he prefers to reposition existing multifamily properties, he has also subdivided land, built homes, and constructed self-storage.

What amount of cash saved is feasible for this option? 

My goal is to convert the existing structure into four separate condominiums, each individually titled and sellable.I would appreciate the opportunity to speak with someone  here about the feasibility of such a project, including any zoning or permitting considerations specific to Cincy, OH.

DSTs are fully passive, 1031-compliant fractional investments in assets like multifamily, medical, or self-storage, offering 4%–6% annual returns with zero management.

Specifically, I’m interested in pursuing a buy-and-hold strategy, and I’d like to understand whether it’s feasible to go full time while self-managing fewer than 10 units—or if supplementing with flips or other income-producing strategies is typically necessary in the early stages.I would greatly appreciate hearing from those of you who are already full time in real estate:What does your day-to-day typically look like?

I totally feel you on the hassle factor - managing furniture wear-and-tear, logistics of storage/sale, and attracting the right tenant for furnished long-term can be a headache.

When you have a family, it's not really feasible anymore. 

Both units have air conditioning, and both have a private storage space in the basement.

You will be very pleased within 10 years  Yes, that actually seems to be the most feasible approach for now — especially when combined with property management.
