@Edreco AmosMiami’s market can be tricky for cash flow since condo fees and insurance costs can eat into your profits, especially with newer buildings or those near the water.

Like @Kyle Mccaw noted there is significant value in goodwill and I imagine you profited nicely over this pleasant long term relationship. 

BRRRR is tough, more difficult than advertised, definitely still a viable strategy, just not a 'cash flow' strategy.Yeah I didn't figure it for cashflow, but more of a piecework operation for profit and redeploying ARV equity with some alternative uses for renting if desired.

When I use AirDNA I do not focus on the algo generated number too much, rather how are the most comparable units doing. 

The ability to find a good sales price under $200K with low taxes and affordable insurance is getting harder to find but in Oh & IN its still easy.Inventory is strong and the rents are above normal so even though your under $200K you can still earn a good profit.

If your properties are generating solid cash flow or have appreciated significantly, you might be following a “smart leverage” strategy, à la Grant Cardone.

I would provide the capital and otherwise stay passive, but hopefully grab better profits than private lending?

But then again, no one ever went broke paying tax on profit. 

Most of the homes we built on these lots sold at a profit, but a couple did not, again, because of the reasons above. 

It's a long-term learning process, but an interesting and often profitable journey - best of luck to you!
