I have a portfolio of SFR out of state, but I am looking to start doing some deals on LI and want to build my network up here.

I am passionate about Tiny Homes, I started just by helping more people with creative floorplans by self teaching myself CAD design so I could help more families.

BiggerPockets is full of resources designed to help you along your journey, whether you are just getting started or a seasoned investor.

Regarding getting started, I recommend finding an STR owner who's overwhelmed or just worn out with managing their property, and perhaps who's also not using a dynamic pricing tool, and then offering to manage it for a very small cost.

Start by being actively involved with your PROPERTY MANAGEMENT duties.
