But I guess no need to be super aggressive on paying down existing student/car loan since there could be other unexpected expenses not accounted for.You're saying the extra $150 in cash flow is too risky given the thin margin?

Get a solid foundation in that by reading, but also by walking through existing projects from other investors and contractors will certainly help!

My team and I are now officially partnered with Home Depot ProXtra with an exclusive discount on-top of their existing ProXtra accounts to help further their ROI ($6,100 average savings --this is a huge game changer for our investor pool!)

In Metairie, duplexes exist, but true multifamily is less common; the area is more single-family focused.

As mentioned, shockingly, there is no option to transfer a listing (as simple as it would be for Airbnb & Vrbo to create).What we do is get the guest contact information and booking details from the previous owner/host/property manager, and draft a message to existing guests from the previous owner/host/property manager, explaining the situation and asking the previous owner/host/property manager to send it to the guest then almost immediatly after we reach out to the guest following up ideally by phone. 

Also, after closing, would I need to place all tenants on new leases since their existing ones were with the previous owner and may not be enforceable?

Your area may be different, where building small MF can be done for less than the cost of buying and upgrading existing.
