Either way its good to buy end of year as most builders and sellers are offering seller credits or builder credits to use towards closing costs or to buy a rate down to help get a lower payment.Even if you wanted to buy a strater home like a 2-4 unit as a primary again you only need to put 5% down. 

In my opinion, your occupancy rate and min night stay seem in the ballpark for planning purposes at this stage.

While the traditional approach involves buying a multi family property, living in one unit and renting out the other - with rising prices and interest rates; others have considered renting out bedrooms as unit spaces. 

The jury is out on summer, but we are already cutting rates significantly to get bookings for our properties.We are currently trending toward 2019-ish rents for most of our properties. 

Discount Brokerages are LOOSING market share not gaining.

We've run about a 20% vacancy rate. 2 of our MTRs have been great, the third we sold after it wasn't generating enough inquiries over two years of effort.

This will give you more time to shop rates/fees than to be under the gun with a purchase loan. 

Play with numbers and today interest rates to see if it makes sense for you since you’re locked in with a good low rate.

You do not indicate what your current interest rate is.  

I'd try to get a 6-month lease at a below-market rate to attract a tenant.
