I do not understand your remark as related to the DSCR loan.  2 ADUs are not allowed by f/f conventional financing but is not always enforced.Fortunately if you stay with the current tenant without a refi, by the time you pay principle it is likely the rent will have increased enough to absorb the increase mortgage payment. 

I work in group home settings for a living and at my previous facility there were two clients per bedroom which would give you potentially 8 in your house while at my current job there is one client per bedroom which would only be 4 clients in your home.

CURRENT FOR SALE.Homes were in disrepair and needed immediate renovation.

Quote from @Kaushik Sarkar: I’m exploring strategies to scale my real estate portfolio given the current mortgage rate Not sure much makes sense at 11%...Ouch....tough enough at 7.5%   Might have to put more than 20% down to finance....maybe 30% in North Texas.   

Here’s a bit of background on my current situation:I own one rental property that generates $1,900 per month in rental income, and it is paid off ($300K).My primary residence is also paid off ($288K).I’m currently building another rental property with cash ($200K).

Knowing your current state comps is a great place to start and a real estate agent can help pull those figures quickly. 

We currently use Hospitable for 12 properties, and it's working fine, no major issues, and I know they've been expanding with new features.

These were financial mistakes we made when we were younger, and unfortunately, they snowballed over time.We currently rent but own a rental property out of state that cash flows $600/month and has about $190,000 in equity.

I currently own 50 LTR units in my local area.

I have high equity in my current duplex so planning on using that to fund down payment for the next property.
