You will need some space for the second unit, preferably close to the first unit, so that tapping in and re-routing the ductwork is minimal.Alternatively, dedicate the existing HVAC to the larger apartment and install a mini-split system for the other.One of the issues with both solutions is that the existing HVAC will be oversized for just the single unit, which can lead to issues with moisture removal during humid periods, but in my case, this has worked fine for several years now.

Personally I prefer the real estate if you ask.

With a preference for multi-family, I am looking to learn as much as possible while simultaneously building as many relationships as possible.

I don't have enough extra capital to invest seriously in all three, so I'd prefer to focus my time/money.So, while I feel confident in my next business idea, I also know that about 2/3 of the businesses I've created over the years have failed to turn a significant profit, so real estate seems like a better way to diversify.Here's the problem: From everything I'm reading, it seems like the cashflow from rental properties is relatively low on average (e.g. $200/month/unit seems to be a common example).

If anyone is interested in sharing knowledge about real estate in general (or the US East Coast market), comment and we can set up a Zoom meeting - preferably mornings or early afternoon ET time zone as I am in London! 

- Or do you prefer to put systems into place?

I meant to mention to you before that my preferred strategy for Subject 2 is to fix and sell in short time frame as you said.

Do you know about Rock springs in Apopka?

It sounds like most investors prefer to put in an offer before visiting the property.

Also I was wondering if many of you prefer to setup the savings accounts in a higher interest online bank (like Goldman Sachs Marcus).
