Conventional or DSCR?

They are also buyer markets since there's an abundance of inventory.

Conventional renting out never makes sense here in terms of cash flow.

@Cameron Porter +95% of the land bank inventory is already picked over by the time it hits the public.The only people we know that have bought ALL went over budget and only the increasing market covered what would have been losses.So, proceed VERY carefully!

The honest ones will tell you there is a ton of inventory and what you will need to invest to try to stand out enough to get huge occupancy and high nightly rates is going to be significant. 

Doing a conventional loan for each property is out of the question due to my debt-to-income ratio. 

You are correct, that this has long been the conventional figure used to estimate cost for buildable sf in NYC. 

It’s given me the opportunity to save and prepare for my next upcoming purchase.I’ve gotten the units from $750x2 and $800x2 to a consistent $900. current mortgage is $2500 monthly, refinancing to a conventional and removing mortgage insurance should bring me to $2100. 

This is based off of the conventional loan limit where you are buying.
