My thinking is that the market will be significantly lower in the winter (Ottawa has a lot of festivals & tourists in the summer).

If you are looking in the clearwater beach area you should not have a problem as this is a tourist area and more of less expected.

Should be located closer to CITY Center, or places which attracts tourist, travel nurses or anything which make sense for MTR or STR. 3.

Look for areas that are popular with tourists or have a high demand for short-term rentals. 4.

I've also sold collectible on ebay, did photography tours for tourists in my city, booked travel for clients as a travel agent, published a real estate book on amazon KDP, sold landscape photographs at galleries, and a few other odd-jobs here and there.

Some good metrics to look at:Median home priceMedian household incomeMedian rent price (specific to bedrooms/bathrooms or square footage)Population growthFor cashflow: price:rent ratioFor appreciation: look for significant economic drivers (large scale employers, tourist attractions, development/construction, employers moving in, etc.)

Different areas attract different kinds of tourists.

The articles below mention the Volcano area specifically getting re-zoned to accommodate STRs since there aren't many hotels to serve tourists' needs. https://www.westhawaiitoday.co...https://www.westhawaiitoday.co...

Is mostly tourist or there any other major retailer  in the area ?

Most 3 bedroom foreclosures go for $9500.You can do your STRs to contractors and tourists.
