Start by pulling recent sales, estimating ARVs based on condition, layout, and finishes, and then compare them to actual sale prices to sharpen your eye.Also worth noting: many local investors start building cash flow by looking out-of-state places where entry costs are lower and rents make more sense.

Great breakdown—this is a critical concept that often gets glossed over when investors first start diving into cost segregation.

Medium size multifamily (I'd recommend 8 units to start) is a good way to get started investing.

Given that you and your siblings have equal funds and are looking for a shared investment, you’re already starting from a place of alignment—which is a huge advantage.

I'd recommend acquisition over construction for someone just starting out unless you are already well established financially.

I also like Confirmation of utilities in tenants name prior to move it. 

I'd start as a Sole Proprietor.

Think of it as matchmaking and getting paid handsomely for it.No loans.No rehabs.No tenants and toilets.Control the deal, connect the dots, and cash a check.Why start with Cooperative Assignments?

and then consider worst case scenarios, if this doesnt cashflow as a STR, can I start financially survive a next best option?

after that brian helped write another couple books through BP wtih Brandon on apartment investing that are decent reads, but candidly crushing it is just about all you need to know to get an idea of where you want to start.
