I was mainly thinking about the effects of putting an entire strong cashflow back into the mortgage.

Their sales pitch is way too strong. 

I strongly believe that with 100% digital collections done via Baselane (including security deposit collection) and it's banking service is such a risky value proposition for investors like you and me, as at some point these type of situations will always happen ... and no one else is on the hook other that you as the owner / landlord.

If your calendar is packed, this indicates you are in a strong market and will quickly make ROI AND you wont have to worry about this issue again. 

Is there strong demand for high-end rentals in your area?

Population is growing and the job market is strong (major employers developing like Intel, Amazon, Meta, etc.)

Based in Miami, FL, they have a strong track record of successfully completing projects.

The idea you can put 5% down and cash flow and have strong appreciation is very rare. 

At the end of the day, assuming the market at a high-level is strong, you must be able to trust in a strong, local team. 

NCM appears to not have been ready for this process since it had experienced a strong market for many years.
