Why not buy each subsequent dup/tri/quad-plex as pure investments from day one?

So it's great that you're doing your own DD.To conclude, if it was me and I was looking at it from a pure investment point of view, my assessment would come down to a low rental yield and a low capital appreciation potential so I wouldn't touch it with a 10-foot pole.

I would just make sure it cashflows as a pure long term rental (non owner occupied) so then you have options after you buy it.

For me, a purchase in Hilton Head would be more about having a second home rather than pure investment.I assume you are looking in Hilton Head? 

I would want some credit towards the purchase price while I am in the lease period.Use a recorded pure option to give you the right to buy the property in the future at a set price. 

My insurance quotes have been huge on my second property (purely rental, first is owner occupied rental).  

As a pure investment, the numbers aren't very good.You can get around the PM requirement out in nearby Toquerville, La Verkin, or some areas of Hurricane. 

I did this, approached some tenants asking their landlords' contact, stating that it is purely for business inquiries not personal harassment.

Overall, just wondering your thoughts on this and what I should aim for as reserves vs. pure cash flow after vacancy/cap-ex.

My approach was purely data-driven with a documented methodology and sources...
