Not a huge increase in cash flow, but you're picking up another appreciating asset. 

When you save up enough capital, slowly increase your portfolio.

Then came investor financial data, I wanted at least a few years in there, I got a totally different-identical answer:"another one of our customers just imported his on his own with our API."

With some changes to the management structure and leadership, I believe we can significantly increase the revenue potential while providing a positive impact.

I have a renter in there now and am wondering if a cost-seg makes sense to do financially as I am planning to keep the place for 10+ years. 

If you need financial help, ask under the "Finance, Tax, and Legal" forum.

-----------------------------------------------------------------------------------------------------------Recommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.Property Class will typically dictate the Class of tenant you get, which greatly IMPACTS rental income stability and property maintenance/damage by tenants.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a property in Class D area to Class A standards, what quality of tenant will you get?

I even try to unsell them on the business by sharing my financial losses, litigation,  market shifts, permit purgatory, shady contractors,  clouded title issues,  paranormal activity, squatters, mold, etc.

Putting that amount into it will only increase the loss.

High ceiling looks great but increases your utility bill.
