The short term rental business has been fine, up until this month where I saw the lowest bookings since opening.

The technical term is Sound Transmission Class. 

However if you understand the process already and what you're trying to achieve and just looking for someone to do it for you, then I would search a bit more to price compare and then make your informed decision.

it's really long.

Looking to invest in long term hold multifamily.

I currently work with investors in the states and out of the states to build a portfolio in Turn-Key, Single-family long-term rentals.

I've done some negotiation with the seller already and we've agreed on the broad terms of the deal.

Then do a thorough research on tenant applicants (note: leaving this to a PM may be hazardous to your financial health) and choose the one that is most “stable” with the best potential for long term tenancy.This advice is contrary to maximization of rental income, but IMO will reduce expenses of tenant turnover, property damage, property management fees so much that the difference in bottom line income will be quite small.  

In 2019, I launched my own revenue management agency to help Airbnb owners boost their income and achieve greater returns on their short-term rental properties.

I'm looking at it long term and will not need the equity anytime soon.
