I did some significant research on this a few months back, as I have identical scenario as you. 6 finanaced properties nd looking for LOC on investment properties.Although, I just ended up refinancing my current HELOC on primary with USBank to tap into huge amount of appreciation during the 2-yrs since I originally opened the HELOC.I believe the best option -locally- for investment property LOC was SAFE credit union.

I was in a nearly identical position when I graduated 7 years ago.

You will also find that it is easier to find property types in the same caste of structural preference.3.Purchase only properties of a similar build: Because the homes I buy are in close proximity to one another, I find it easy to repeatedly select similar, if not identical structures.

If so then you may/could be entering the realm of a non-arms length 'identity of interest' deal & potentially mortgage fraud, so any fear of a taxable event would be the least of your problems.

All were nearly identical square footage and similar in condition (fair/required minimal-moderate rehab). 

@Joshua BiondiBuying from a relative or someone a business relationship with FHA falls under "identity of interest."

You could also opt for a family name, such as Miller Ranch or Hannah-Coy Estates.You'll also need to think of a brand identity, which is the home's personality, both in “real life” and in your marketing materials, including the logo and website.

I could have paid a lot less for an identical property with a tenant included.

Your experience is almost identical to hundreds of investors I've spoken with.

Have not reached too far with banks on the commercial side yet, but wanted to make this its own LLC identity separate since it essentially is a new business model for us.
