Hey Tre,
i'm not sure where you work or if you have a preference for location but i have a brokerage buddy who just locked up a househack in Athol. Units are cheap and they just put a Starbucks in so there's got to be something growing there.
North of Worcester ie. Lowell, Fitchburg, and Leominster have cheaper units and aren't bad places to invest.
South of Worcester ie. Southbridge and Webster are cheaper as well.
There will be obvious trade-offs in terms of location / amenities and price but i have seen good traction in all of the aforementioned locations.
I'm looking for househacks for clients around central Mass and while they're not impossible to find by any means units in Worcester are typically trading at $225-250. It's a very competitive market there.
I think your 203k approach will likely be a leg up in deal hunting as you'll be able to take on an investment that needs a bigger scope of work while others might be looking for a more standard value add situation.
let's connect. i'd love to help however i can
