@Stephen Hood your idea is solid and shows good potential, but here are a few things to consider:Private Lender Terms: Ensure the lender agrees to the 1% origination fee and $2K monthly payments—some may require a higher interest rate or balloon payment at the end.Timeline for Sale: Factor in potential delays with selling your current property or completing renovations on the new one, as these could impact your refinance timeline.Refinance Feasibility: Confirm with lenders that refinancing at $500K is realistic, especially after recent rate increases and appraisal expectations.Exit Plan: Have a backup plan in case the market shifts or repairs take longer than expected, such as extending the private loan or bridging with a HELOC.If you can lock in favorable private loan terms and stay realistic about costs and timelines, this could work well.

yes it would take a retooling the industry and industry standards no doubt..

Also, have you made any significant alterations to the property or if it were put on the market today, would it be indistinguishable from a standard 4-bedoom house (are there any extra walls for the SRO, constructed locks/barriers etc.)If its a standard SFR and the leases are very short term - there is a path that you could refinance this with a DSCR as basically a Short Term Rental and then potentially change strategic course back to SRO if needed at a later date

either by increasing direct profits or creating growth or both.

There are many other angles also you can take to both increase profit, reduce risk, etc.

With a triplex, the cost for the same slab increases only slightly, to $28,000, but you get three units instead of one.

I stand corrected:)They do have an office in Metro Detroit and while we're far from perfect, we seem to get a lot of their unhappy previous clients.In our opinion, they built a system for Class A rentals - where tenants have 680+ credit scores and rarely have to be evicted or trash properties.They then tried to apply their processes to Class B & C rentals and that's when their service issues increased.All this caused them to recently significantly increase their Flat Fee pricing and monthly minimum charges.

It would seemingly also increase what I could get for rent, has anyone found that to not be the case?

A standalone ADU is almost always going to cost more than doing an addition, so the value added or cash flow increases will have to justify each.I work with a team of investors who will buy SFR homes then build a new ADU on the lot and add a separate drive way and meters for utilities in North Texas.
