Or you can sell several small properties and "consolidate" into fewer more expensive properties.  

etc.I have come across a lot of great resources on BP but I am looking for something more consolidated.

I’ve spoken with two credit unions in my area so far, one said they’d only provide a HELOC for debt consolidation and improvements to a principal residence, the other would allow for repairs/improvements to a non-principal residence but still would not allow the money to be used on a down payment for an investment property.

Would a HELOC be an advisable option to consolidate that credit card debt?

If you have multiple accounts with the same company (for example, a Southwest credit card which is through Chase and a Chase Freedom Card) you can consolidate your credit lines so you can access whatever rates/offers are best at the moment!

Paying off a home sooner, opening a new credit card, consolidating, trying to raise your fico right now aren't going to help at all at this stage IMO. 

They started long ago acquiring and gradually transitioned to consolidating in a couple geographies and then managing their holdings for about 30-40 years before selling out for $140 Million. 

I can trade 2 or 3 properties for 1 (consolidate) if I wish and have no recapturing of depreciation.Otherwise, I plan on DYING with the properties.  

Consolidation!!

We still invest in residential multifamily built 2000 or newer in markets with larger quantities of these available to consolidate management companies.
