I'd love to hear more from you.Residential Districts (2019): Renting properties for periods less than 31 days or a calendar month is prohibited.

On top of that, many policies have become more strict (especially in the last few years) with replacement cost language because replacement cost estimates did not keep up with inflation for a period of time AND/OR replacement costs on many older properties had skyrocketed so it made more sense to calculate replacement values with functionally equivalent rather than exact materials.

So Bank, when writing a loan, must ensure that property's worth is greater than the loan extended, so if and when borrower defaults they can foreclose on the property, auction it off and get back the money lent.

This is the tenants responsibility, period.

The seller must think he is sitting on a really hot property, or the buyer is asking for too long of a DD period.

Were they all completed within the same 12-month period, or did it take longer?

Additionally, Airbnb income during this period could generate steady cash flow, though market conditions and regulatory risks should be considered.

Keep in mind that they can increase that period if they get complains from the community, so make sure you're in good relationship with your neighbors.

My draw down period is ten years of interest only payments then twenty years principal plus interest after that. 

In judicial states in which the foreclosure process often takes a year or more, this not only generates income, this also typically mitigates property deterioration, vandalism, and other costly issues which diminish the value of abandoned properties which remain vacant for extended periods.
