Currently I am taking my real estate courses to achieve my license so I would be able to invest and learn more about real estate.

You are training the tenant on exactly how to $crew the next LL.  

Of course there could be some other local businesses that might would want to use or share a couple of the offices that would possibly increase revenue. 

Of course there is a lot of research to be done.

Imagine making millions of dollars over the course of your career and then having to pay 30-50% every year to uncle sam instead of compounding that cash over time.This is exactly what real estate professionals have learned to mitigate.To reduce their taxable income, they just buy a building every year, do a cost seg, and use depreciation to reduce their tax liability dramatically.Their personal wealth snowball grows much larger and much faster than their W2 counterparts who give most of their money back to the government each year.Following this strategy as a real estate professional is one of best ways to end up with a much larger net worth at the end of your career.

Forget the course and put that money on a quality vacation short-term rental.  

I think it would, depending on the celebrity of course. 

And of course, take advantage of the tax benefits along side my current business income.Viability of the idea?

If you're located in WI, check out Premier Point Realty and Homestead Realty....both offer the licensing course at a discount and some of the lowest fees/commission splits in our local market.

None the less, I come from a background of training people for a living and it comes naturally to me to help others get started on this amazing journey called "Real Estate Investing"I started my cash flow real estate investing journey In January of 2023.
