I worry on finding good deals in Tampa and pulling off a successful rehab with the current supply chain issues.

We knew the area and had an excuse to visit regularly.

Is there any rule of thumb for looking at a regular house rent and converting to a duplex rent for comps? 

The good part of this for me is about supply and demand.

Each partner earns $14,000 per year in regular income.

The best way to start investing in Real Estate is to have a regular job that pays the bills while starting your investing career as a side hustle.  

This tenant were there for more than 2 years and been paying regularly however due to COVID moratorium, they went on the other side and we couldn't evict until recently.

You can probably get another 10 years+ out of it at your current usage, assuming you're running it regularly to keep it running smoothly.

The SB and AB's that were passed for ADU's were much more effective in creating additional housing, but still just a drop in the bucket for what is needed and the costs to build the ADU's are skyrocketing each month due to labor and materials costs, not to mention material shortages due to supply chain issues which are getting worse, not better (that's across the board for all states, not just CA, but more heavily felt here as Long beach is a HUGE port not currently even close to full operations.)

I find it quite regular to see unrealistically low Property Management expenses presented by the Seller.
