Imagine if the investors approached it as a work-shop to co-op networks, ideas, resources to change direction of things.... 

I own BRRRR properties in Colorado, but now looking to invest in Portugal, and run a group for mostly British & American Expats in Coimbra - some of which would be interested in Golden Visa investments.

I would also note your mention of not wanting liability, but offering to "co-sign".

I have changed my rental strategy to short-term rentals and co-living (rent by room) to allow for more cash flow. 

At a certain point it becomes a lot of work but you can outsource a lot of the work by hiring VAs which is way cheaper than a management co (definitely not as hands off though) 

Assess Your Goals and Current Structure: Beyond replacing your handyman team, it’s important to evaluate your portfolio’s current management framework and clarify your long-term objectives.How are responsibilities currently divided among you and any co-owners or family members?

You can get similar returns with co-living (padsplit ect), but that will likely not be a long term solution for you since you have not enjoyed being a landlord. 

This is colorado springs areaThank you.

I'm a realtor from Colorado who wholesales STRs nationwide to help investors get big tax deductions.

Fast forward, my brother and I co-founded a property management company in Boston, where we handle everything from tenants to transformations.
