Liquidating these to focus heavily on real estate removes this safety net and exposes you to sector-specific risks.

Not that its impossible to get creative financing or that its bad to start investing I'm not saying that by any means at all the earlier the better but the safety blanket is small with no reserves for an expensive learning experience which in this industry is likely. 

We include the cost of all the smart tech we want installed that the homeowner keeps, safety items we require in each property, and the items/signs we use to "brand" the home to our company, as well as our time setting up the listings, pricing, guidebooks, auto messaging, cleaning up the supply closets, kitchens, etc.

Does anyone know if North Linden area in Columbus, Ohio a good place to invest in for long term in multi unit (6-unit) apartment buildings from growth and safety standpoint?

If it was built before, say, 1960 there may be a slew of electrical work you'll need to do to stay in regulations with current times and, of course, for the safety of a future buyer.

Think mini pensions or rental properties that provide steady cash flow.However, if your net worth is under $4 to $5 million, you’re still in growth mode and should keep your day job.

My thoughts on the HELOC are that we could use it to renovate our current properties and use the funds to fix up distressed properties in the future(doing BRRR-like activities) and thinking it could be used as a safety net if needed. 

I dont think you can call it totally passive if someone does that they are probably going to make a mistake you need to work the loans and put time into them to ensure all the safety items you mentioned.2.

I’m about to transition into beginning of the school year mode, but I’ll keep it in mind!

That is correct @J Scott as my entire business model is based off your books.
