Takes just a minute to set new codes and can easily create codes for maintenance/cleaning/delivery people and then see when they arrive.I also put lockboxes at each property for the rare case where batteries may die or power is out.You can get them on Amazon or on eBay and are often on sale.

Most of my markets generally prefer clean and modern compared to all original restored.

OP is referring to how the subject property was titled... which has no effect on how the lawsuit against his "partners" should be handled. 

BARRRR is in full effect, but unsure whether I should refi and cash out a bit. 

For me it's all about having a great cleaning person/crew.Homeaway and Airbnb make it easy to keep an up to date calendar, accept payments, refund security deposits.Then nice to have are automated locks (I still use a lockbox), security cameras, wifi thermostats.You need great pictures and descriptions, you need to be responsive to inquiries and issues.You need a great location so that you have demand at your property.I think this is the Cliff Notes version.Take up Lucas Carl on the phone call.

I have seen a few "Gurus" talking about using a HELOC to pay large chunks of your mortgage and then use your HELOC as a checking account and put your paycheck into the HELOC to help with payment of the HELOC, or something to that effect.  

Does having more units in a rental property effect how much you would want in your cash flow?

It is a quaint idea... but effectively no such thing.

Use this trick as last resort so it doesn't loose it's effectiveness.

It will also depend on what state you are in as to whether it will be cost effective or not.
