To mitigate concerns of placing a bad tenant, set your application guidelines as strict as you need to feel comfortable, and STICK TO THOSE GUIDELINES.

There are several turnkey providers in town or investor friendly agents like myself.

We provide for example finished basements for that exact reason - not because it yields more rent, but because tenants stay longer.

What types of tenants are you comfortable managing? 

Can lawyer provide you with an early termination agreement where they release you from liability?

A heloc in my view is best used to provide the down payment and rehab funds, rent, REFI, repeat.   

In fact many of our properties are done that way - we get a signed contract and then turn the package over to the closing attorney and move on to the next one until closing day.Your local REIG can recommend some good closing attorneys / title companies and they will usually be happy to walk you through the process and even provide you with the forms you need to get the deal locked up and closed.

You have an opportunity to start with a clean slate and hopefully choose the type of marketing that provides the most effective and efficient use of your money and time.That being said, there are plenty of program marketers selling complete packages costing $8,000 a month and up, with a 12 month commitment.

I also own and operate a business that provides water submetering for multi-family properties of all sizes.

Unfortunately I think nowadays they just go on Airbnb/VRBO and select/negotiate with hosts they find on the sites instead of seeking out providers.
