@Andrew Freed very popular here!

In fact I can’t think of any RI-specific sources that would only apply to RI and not other states.Classic strategies for finding motivated sellers include direct mail, SEO/web advertising, telephone pole (aka “bandit”) signs, door hangers, driving for dollars, etc.As far as getting lists to direct market to, buying them from list brokers is popular, as is driving around yourself, trawling public records sites (see ripropinfo.com) etc.

I bought a home in 2020 in a popular market.

I mean, I know it's popular on BP, but...:) 

More than likely it isn't an area where people want to go so you don't see the numbers you would in a more popular area.

As some have already mentioned, Point Breeze and Grays Ferry are very popular with investors.

Gray's Ferry according to this novice real estate investor.Fishtown pros - proximity to major highway and transport lines, shopping of all sorts nearby and fair share of boutique pro chef restaurants and micro brew style bars, name already seen as hip and flippers proving buyers will pay a premium to move.Gray's ferry pros - major hospital and university expansion started just a mile or two away, prices still mostly accessible, near major highway and transport lines. cons: doesn't carry the popularity of fishtown and still seen by most as street-by-street, there's little or no shopping and certainly no restaurant or hip bar scene.My current strategy is buy and hold for the long term.

Astronomically high housing prices but it's also an incredibly popular tourist destination so I'd imagine that the short term rental market would have to be the market to go after in Hawaii.

Brewerytown caught my eye as it is close to center city and in the lower part, it seems like there is less crime and gaining popularity.  

Scaling, I really like the thought of BRRRR but I wonder what other popular methods of scaling are being used?
