Just to be clear, the $25,000 is a fine for failing to submit your IRS 5472 form, it's not going to be imposed if you file properly!
I wouldn't be discouraged by the above. I have set up an Arkansas single member foreign-owned LLC online from Dubai on a shoestring budget. Getting the Employer Identification Number from the IRS was free, and once I had that I could open a new bank account in USA remotely. I pay $50 per year for a registered agent, $10/month for mailbox that scans my mail and sends to me, and $10 for a USA phone number connected to an App.
It's a lot of extra work, but in my opinion the opportunities are worthwhile. I'm using virtual assistants from Upwork to help me with my bookkeeping and property research, and using this fantastic BP site makes it easy to connect with agents/property managers/contractors on the ground where I'm buying.
I'm only just getting my first purchases underway now, so I don't know how much tax I have to pay. But presumably, it's only going to be on my profits, so there is not a huge downside risk there. If I didn't do this, I wouldn't have any profits! I'm a lot more comfortable investing in real estate than shares or funds that I have no control over and where their value can change overnight.
