Only thing is it won't be easy to track especially if you have a 10 unit and all the rents are all $450 a month. 

The reality is the opposite - if it's not in writing then the PMC doesn't have to provide the service or can charge extra for it!

That's because the city won't calculate the actual amount till a structure is built, aka it's not just a plot of land anymore.This will obvious cause your property tax bill to go up and also your mortgage escrow account as well (sometimes these things can make your mortgage shoot up a few hundred a month). 

My experience has been that most lenders don’t immediately move on this, many don’t take action for 6 - 12 months.  

Great PM. check came in monthly.

Points I can roll into the cost and don't mind a buy down if necessary.My primary concern is the bleed rate monthly for the build, Airbnb stabilization and the year after while we season it and prep for final financing for long term hold.

My goal of refinancing was simply lowering our monthly spending to reallocate towards future investments.

The calculator estimates that operating expenses are equal to 50% of the monthly income.  50% is a rough guide. 

January is historically the lowest demand/income month so when a cancellation happens it hurts more.

I originally started as 80% LTV and 12% + 1 point with 3 month prepay penalty
