However, I made the error early in my career of thinking I was generating way more cash than I thought I was. 

A formal business built on this seems overkill as you’re essentially paying someone for a service that already has standard model.If you and the parnter have distinct business tasks/abilities (i.e. not what you would hire an agent or contractor for), such as off-market lead generation, that’s a different discussion.

In recruiting, it's called running a 'full-desk', when you generate your own clients, and then place candidates directly in them. 

During this time you are not generating any return from the money invested in the ADU.

Instead of 40 houses cash flowing $200 each or $8000/month, you buy 10 houses and pay them off for a cash flow of $10,000/month with 1/4th the headache.People don't understand the amount of time, energy, and stress involved with managing a lot of doors, especially if they are lower-class properties typically needed to generate cash flow.

What may the property be worth then and how much cashflow might it be generating?

If the market rents do not cover the mortgage, you may do a no ratio DSCR for a higher rate/reduced LTV  Which most likely the 1007 will be nowhere near the revenue generated by a PadSplit operation.

With this, along with shifting the utilities to the tenants and reducing the management fee to generate an NOI of around $103k, I'd estimate the value around $1.8M to $2.0M

Even if I were to rent it out on Airbnb, the cash-on-cash return isn't very attractive.Specifically, I’m concerned about:High mortgage payments and the financial strain it could cause if the property doesn't generate sufficient cash flow.Cash-on-cash return is low, even with high-revenue short-term rentals.My Questions:Risk Mitigation:Any strategies I can use to mitigate the risks associated with owning a high-value property with a large mortgage?
