Personally I dislike HOA's, scale deliberately and dont overleverage.

That presents a great opportunity, however it is hard to scale when buying everything with cash. 

I want to scale, but all of these loans make it very difficult.

If such a worksheet does not exist (and it may not exist in a consumer-grade tax software, sorry) or it exists but is hard to figure out, then you might need professional help.

Truth is low grade properties are not profitable unless you self manage and get work done for below market rates.

I have an opportunity to construct a mixed-use building with 42 residential units (each around 600 sq. ft. with 1+ bedrooms) and 2 commercial spaces, totaling approximately 42,000 sq. ft.We have a solid understanding of constructing smaller projects, such as 2-4 unit buildings, but this larger scale is new to us.

Larger, experienced shops likely less so, but with these groups even if they have some problem deals it’ll amount to a headwind to overall performance of a very large portfolio rather than a disaster that brings down the firm.The 2020 to 2023 period saw several very active “newer” groups who were rapidly scaling and in some cases dominating acquisitions.  

I don't have a job yet and I'm about to start 10th grade, but I'm hoping to get experience in this market as soon as I can and to create my network model.

If you make certain your buyer is pre approved, the documents line up, and you keep good communication, the selling side has never proven to be difficult to me.With that said I agree with @Rick Santasiere in regards to scaling up.
