Is it in an area where assets have been or you believe will have appreciation? 

And over time, as those assets to make our product we sell had a fixed price, the dollar does not sit fixed, our cost of product increases meaning increased cash-flow.

But if you're willing to take a tiny leap of faith, I think the returns are solid, the diligence and the integrity are there, and the states/markets/submarkets and the asset class are thumbs-up.

A financial advisor or real estate pro could help you map it all out more concretely.If I were in your shoes, I'd probably lean towards selling and reinvesting into some more diverse assets, or just more properties, but that's just me. 

Assets - you need these, or you need partners.

Hypothetically, if I found a property with strong rental demand, the income could cover loan payments, operating expenses, and generate a modest positive cash flow.While this example involves upfront risks, the idea would be to leverage my father’s expertise as a contractor to minimize renovation costs, boost the property’s value, and create a long-term asset that appreciates over time.

But this way you have appreciating assets paying off your appreciating asset.

Focus on the physical aspect of physical assets. 

Additionally, in the R-7 and R-8 Zoning Districts, you need a Conditional Use Ordinance from the City Council to authorize the conversion.

It may not appear this way on the surface but you are going to come out ahead by focusing on purchasing fewer but quality assets rather than becoming a door accumulator.
