What methods would you suggest to screen potential tenants? 

However, anything that impacts functionality like plumbing, HVAC, or safety issues should be handled before listing to avoid turning off potential renters/buyers.If you’re re planning to lease it, tenants will expect everything to be move-in ready before signing.

Find Brandon's videos on YouTube for the "four square" method of analyzing homes and practice.

One of the roadblocks weir running into is the potential tenant will keep communication and go silent once we bring up background checks.

If you plan to use the remaining HELOC for a DSCR or BRRR strategy, that could help you build more equity, but consider if the current market conditions will lead to higher rates and lower cash flow in the near term.If your goal is to scale, you might consider holding onto your current duplex for the cash flow and focusing on the BRRR/DSCR strategy, which can allow for more control and potentially better long-term returns.

You can still find positive cash flow (aka the 1% rule) and amazing appreciation potential.

The remaining potential issue is their rental properties.

EDUCATE YOURSELF - yes, it will take time, but will lead to a selection that better meets your expectations & avoids potentially costly surprises!

Definitely a good overall real estate market with solid upside potential. 

Additionally, your retirement accounts offer some protection from potential lawsuits.
