Do you have a co-signer that would qualify for amount and trust you to handle a deal?  

However, if you would need to take out a second mortgage on a portion of it, what you would need to find out from the lender is how they would work with a co-op mortgage broker.

This summer I purchased a single family property with a co-worker and we are almost done with renovations (which were MUCH more extensive than we first thought). 

With just a single property Airbnb profile, it was very simple to add them as a 'co-host' and then simply add their bank account to the profile to receive payments.

I have crunched the numbers on condos and haven't found a way to cash flow, unless you use the condo for a STR or do a co-housing (rent by the room) strategy.

(sidenote: I rent to a co worker and give him a break because I know he will be a hassle free tenant.

I have a co-op in Manhattan that I want to sell.

It never hurts to have excess reserves for whatever rehab you line up on your house hack if you have to wait.You may also consider a co-signer from a parent or relative if that is available. 

As a beginner, you can learn a lot from your uncle with a few rentals in another state or a co-worker that's on their second house hack.

Or just have a co-owner?
