There may be options to consolidate all of your properties under 1 loan, for example. 

I vaguely remember, a very long time ago, debt consolidation companies using HELOCs to consolidate credit card debt and doing something like having your paycheck deposited into the HELOC and paying bills from there. 

But I would assume it will be $200-$300 when they consolidate.

It seems to me that it would be much easier to have the debt consolidated under 1 loan, plus the fact that I will be writing off this vehicle as an expense of the business.

You are likely to find a lender willing to consolidate the loans, I think you can get up to 5 with a traditional lender, a more experienced borrower here could say for certain, even if they're not attached to one another. 

After the first property, I will invest in more long-term multifamily properties and after 10 years I will try and consolidate most of the properties with a 1031 into a larger multifamily complex with a property management team!

I can "hear" his attorney advising him to file bankruptcy to consolidate the lawsuits and deal with this mess. 

In general, consolidating multiple multi-family properties into a single LLC can be done, but there are several factors to consider, including the 1031 exchange funds and the desires of the property owners.

Everything I've been seeing and hearing has been 4+ because it's considered a "cash-out" to consolidate the HELOC into the first when the HELOC wasn't taken out as part of the purchase.  

You can use Zillow or other websites like that, but it's a lot harder as their information isn't as good or as easy to consolidate.
