Rent control laws are market specific.

We bought for 130k, put about 45-50k into it and the market is showing we should be able to sell around 300k. 

It by no means is an exhaustive search but I also haven’t seen any co-op communities selling for 50% of comparable condos.I also know lenders that have originated loans for the co-ops in Laguna Hills and I was also reading how Fannie Mae buys mortgages issues to co-ops so it sounds like there’s a market for both qualified and non-qualified loans.

Study the market.

It sat on the market and dropped in price a couple more times at which point we decided to make a new offer.

I am not sure how much you get involved but do your employees contact the realtor and discuss market rents, do the math to check leases versus market rents and which lenders use the "lesser of the two".Closing in an LLC versus personal name can also add a rate hit as well as Escrow or No escrow.

Are you looking in other markets outside of NY? 

If all of them have a garage and yours does not that will either put you at a lower ARV then what you thought, or a longer time on market.

Congratulations on jumping into the STR market.
