We've owned many 20 space parks over the years, and the key items to consider are:1) They can be hard to finance2) They can be hard to sell due to scale3) They can be hard to manage since you can't afford to hire very good talent4) They are too small to weather any big hits in cap-x issuesSo for this deal to work you'd want to have closer proximity to the park, city water and sewer, and no POHs. 

The session rooms were tight and scheduled kind of tight which made it feel like a race and didn’t leave much time to linger and chat.

Many old ranch houses do not have enough closet space.

Most cities and/or counties have a size limit so just build up to your limit and maximize usuable living space if you can or do a two car garage below with living space above the garage.

They will have the front door entrance through the common space.

You're probably looking at $400k+ at this point for a 2 family in Union City in almost any condition, unless it has some of the aforementioned issues, and, with renovation, that can make cash flow tight (certainly depending on size/condition/location).Happy to lend my thoughts if relevant, feel free to shoot me a PM!

I'll definitely keep that in mind when I'm looking for new property managers - I'm working on getting into the small multifamily space, and definitely don't won't do manage all of the additional units I plan on getting in the next few years!

Are the utilities set up for the additional 5 or is there just space for them?

If your numbers are tight to begin with, anything going wrong at any stage -- purchase, rehab, renting, refinancing -- can put a strain on the deal.Don't do the deal if you don't have reserves and can cover holding costs.Expect 8 months of holding costs because typically you can't refinance until 180 days post-close, and then it takes maybe a month or so to actually refinance from there start to finish.If you can't BRRRR comfortably (e.g. leaving money in the deal or not cashing out) then it may not be a good idea until you're ready.Most lenders will be around 70% LTV, not 75%.

@Ron Singh Is there vacant commercial space in the building?
