I think you just have to work it in as the cost of doing business. 

Scotia Bank in Costa Rica will allow you to open up an larger account as 'business owner' if you own your properties in an LLC but the process of opening an account is much more difficult. 

I figure this would be really helpful for anyone in our business.

May not be your cup of tea but they are cost efficient and they work to add passive income at a fraction of the cost to build a SFH.There are a few "Tiny Home" builders in Tampa and Manatee doing a ton of business.  

And all of that with training wheels, it is very hard to screw it up on a consequential scale.Because it is 2025 and RE is not cheap anymore I will encourage you to also look into building a business on the side.

If you find a solid, boots on the ground realtor/PM who has experience in the flip business you should be fine. 

If you're an investor Broker / Property Manger in this business you get 100's and 100's of investors reaching out to you wanting to spend the day with you while they are in town.

You are starting a business. 

The best way to grow your business is to help people and give solid advice in the forums.

This is the cost of doing business.
