Once you get to around $14k you're going to scale up to $37% but you can deduct half the expenses and depreciation which will reduce your taxable amount of income..again without knowing the income this is not possible to calculate.   

Is there a faster way for me to scale?

And the majority of commercial lenders have rates in the 6s or 7s right now for most real world scenarios, and being overly worried or concerned about if it's 5 units or 500 units is absurd, both the rents and the loan size will automatically scale up and down accordingly (if anything, the larger unit counts scale better, so limiting someone to X units makes zero sense).

JV is best as you scale quicker But need to do due diligence

Hello fellow investors,After running my real estate company for 10+ years, and completing numerous value add plays, I am looking to scale up and go after bigger (commercial) projects. 

Scale up!

Go find the hourly rate for someone to install a doorknob, the price of a doorknob, then insurance at scale divided by 30.

My goal is to create a business, hire talent, and scale within a 1-2 year accelerated plan, ultimately achieving my 5-year vision.

This will drive how much you can borrow.Consider More Modest Options FirstWith $200k in investments to deploy, look at starting with 1-2 short-term rental properties first to gain experience before scaling up.Explore markets closer to your mom's current location that may have lower costs but still tourism appeal.This allows you to validate the model and your ability to operate short-term rentals successfully before risking more capital.The short-term rental concept could potentially work, but I would recommend starting with a smaller, very well-researched first step to validate the model before going all-in on a larger endeavor.

One thing though , using an LLC makes you get Business Line Of Credit and also Business Credit cards which helps you scale.. you need to know though to manage good debt!!
