@Olivia Hansen,
I only have one property so far and it is in Whitefish. It is a short to longterm furnished rental. It's managed and after the management fee of 15% (vacation rental) it does still cash flow (barely).
I would stick to Kalispell for better cash flow. There is a shortage of homes on the market and in WF you'll be paying market rates for just about any home. In Kalispell there are plenty of older homes where the BRRR would work really well.
One macro word of caution for the Flathead. Land is plentiful and new construction costs are often lower than existing home prices (right now). I would make it a point to use both the normal sales comparison approach as well as always doing a cost valuation approach. Right now you'll probably end up with a lower value for the cost approach and I would work your numbers from that starting point.
Market cycle home prices in the flathead are a bit amplified at both ends. The second homes end up being the first to foreclose or be sold in down cycles and the resulting deluge of inventory tanks prices. The same well-to-doers bring prices up in good times like we have now.
I wouldn't count on strong appreciation over the next 5 years. Home building in the area is ramping up, close to matching demand and that's going to slow further run up.
There's deals in Kalispell, east and west, but I bet better Caps in West. I wouldn't do multifamily over a quad here either.
Best of luck and check out Desoto Grill in Kalispell. One of my favorite eats in that area.
