I literally started my real estate idea by considering buying property in Japan, but eventually decided that the US made more sense.

Considering your situation, it can be wise to keep your 9-5 job while you develop your real estate knowledge and network.

@Greg StrunakA good real estate accountant can save you thousands of dollars by leveraging entity selection and formation, tax deductions, cost segregations, bonus depreciation and tax planning.I recommend finding an accountant who specializes in real estate taxation, business taxation, financial planning and tax planning.You may want to consider working with your accountant remotely to expand your options.I would also recommend looking for a accountant willing to work with you throughout the year.

Something to consider, if you haven't made a decision yet, are intangibles.

I've considered a property management company, but the cost just doesn't seem worth it although it would be convenient.

It’s a lot to keep track of, especially when researching multiple markets.Would greatly appreciate any advice/insights from experienced investors who've navigated these challenges :- How do you approach understanding and evaluating short-term rental regulations when considering a new market?

I guess it's just too many factors to consider and it easy to get overwhelmed and cannot get accurate info and estimation when I conduct analysis (ex. property tax rate, insurance, maintenance fee, rent, repair, closing cost, etc.) 

That's a pretty low offer you're considering.

I am considering starting a new real estate business in the Denver area and would love some feedback on the idea.

My customer service sector manages a lot of my internal affairs and we've undergone many changes during this ongoing pandemic that have disrupted business.
