There's a lot of growth in the market from major tech companies expanding their business in the area.

For an exchange, they want your intent to be that you hold the property for long-term business or investment use (for both the property you sell and the property you buy).  

Especially since people have realized they can turn it into a business and not a hobby. 2 - i dont see people turning their primary homes into Airbnb's. they need to move, they sell them.

Well, you could always go for "Nunya" as in " Nunya damn business" :) .

What you do with your money is your business, except the IRS wants its percentage of the profit (well, less any other deductions that apply).Don't forget that investment properties have to take depreciation. 

You will need to qualify as "real estate professional to do so" Which simply put is spending 750 hours in a real property trade or business, and more time in that line of work then anything else.

Which in turn will bring plenty of other investors and general business to the market.

And last summer I made around 10k each property each month in busy season.

I think more and more Realtors will leave the business, which is great for those of us willing to put in the work and navigate the changes so we can still help people buy homes.

Have you reached out to local businesses, schools, hospitals, etc.?
