If you're planning on living in it for at least part of the year, a second home loan would be a good option. You can rent out a second home, but you have to intend to occupy for at least part of the year. This is more commonly found with STRs. If you think there's a good chance you'll rent it out as a LTR, you could pay "cash" with the equity in the farm via a HELOC or cash out refinance.
Which route you should take depends on what rate you currently have. If it's lower than you'd get with a cash out refi, it's probably a better idea to do a HELOC. Draw enough to purchase the PA property, and do either delayed financing or a cash out refi on that property if it needs any sort of work. Loan type at that point would depend on occupancy - you could do a second home, investment, or something like a DSCR loan if you don't want your employment/income/DTI factored in. You've got a few options.
That was a LOT of info and your head might feel like it's going to explode.... so if you have any questions or need something explained, feel free to reach out! Happy to help.
