You just want a hub for your business so that if people look you up, they get a point of verification.

@Yang Zeng Welcome to the Bigger Pockets.As you can see in my profile, my business and hub is in San Diego, not far from you, but all our investments for myself and my clients are in well performing markets in the Midwest.We specially in this out-of-state- approach that really requires more than just the properties.I agree that you should keep a reserve and not spend all your funds but I could help you with 6 properties that would pay you about $5K/ month in cash flow or $60K/year based on your available funds while having about $100K reserve.I like to help you see the performance difference between our area in CA and the Midwest.

There are multiple factors to consider, especially in Los Angeles where not only are there sub markets and pocket neighborhoods, but also hubs that drive variation in rent (consider hipster stretches in Silverlake, Highland Park, Echo Park, etc.).

There are huge warehouses on 35th St. next to the interstate (Chewy, Fed Ex hub, Autozone, and another warehouse being built currently). 

Indy is a major transportation hub for the country making distribution one of it's leading industries.

Think isolated towns that are still a hub for rural communities, have a decent medical base, a college or two or three or military nearby. 

MTRs can offer a nice balance between the steady income of long-term rentals and the high cash flow of STRs without the constant turnover.In terms of locations, I've noticed that areas close to hospitals or corporate hubs tend to do well since travel nurses and professionals on temporary assignments often seek out these rentals.

If it's a "vacation rental hub" I'd call local regional banks and ask if they have an insurance broker.

Barrat Assat Management - Indianapolis Indiana (B+, B++, A- multifamily ) - I am fond of this area because it is a logistics hub, Amazon is building a new center here and there are lots of great jobs. 2.

In general, I have found the rent price-point of $450-$500/mo to be a very transient and higher headache tenant hub.
