$500k for a few acres? That won’t get you a place in RI, especially close to Newport. Realistically you’d need to up that budget significantly. RI doesn’t have large lots of land with small farm houses with lots of space for horses to roam. Maybe you can find that one place and get lucky, but your best bet is to contact a reputable agent… reputable. This sold 2yrs ago for $580k and it would’ve been exactly what you were looking for. So take this listing as a good point of reference.
