Make sure you know the value the ADU will add to the property before building the ADU. 2) the financing on an ADU is typically far worse than for initial investment property acquisition or is often not leveraged by the ADU (HELOC, cash out refi, etc).

I work with a lot of MTR investors and what I am seeing frequently with multifamily acquisitions, particularly with new investors, is that they often test the property just like you're mentioning, as a way to dip their toes in the water and see what works in their area and for their personal style.

We didn't buy much from the MLS and if we did, it was either a "handyman special" or it had been on the market 180+ days with a motivated seller willing to take less than market value.This will be the "new normal" going forward and a lot of newer investors will drop out of the acquisition market and just hold what they have.

Welcome to the BP Community and most folks I know that are in your same situation with properties in 1 or more LLCs end up refinancing those properties into DSCR loans (instead of HELOCs) to extract the cash they need for their next acquisitions.

Quote from @Jonathan Grzeszczyk: Soon I am taking a job with a wholesaling company on the acquisition side of the deal. 

If it’s at or near 70% we dig into the full cost model that accounts for financing costs (hard money and GAP), acquisition costs, holding costs and selling costs.

Value is currently $700k more than my acquisition and rehab cost and it has some small positive cash flow (~$5k/month). 

For cash-on-cash evaluation of rental properties, it is critical to identify ALL of  your acquisition costs. 

Do what you say you're going to do, on the seller side and your buyer side.I've done acquisitions for a few years now and I understand how to analyze and close deals pretty good along with having a fully operational running business (from TC, dispositions, etc.) to handle new contracts and get these contracts to the closing table.
