Cheap materials, contemporary designs (again, cheap) that are not compatible with the area, horrendous locations.4. 

The challenge is that Tampa only allows one ADU per lot, with a max of 950 sq ft of total livable area for that unit.That means I technically can’t create a second unit, but I can expand the existing ADU, as long as the combined upstairs + downstairs area stays under the 950 sq ft limit.Here’s where I’m stuck:- I could design it as an “extension” of the ADU (same address, one unit on paper) and just have a kitchenette downstairs instead of a full kitchen.- Each level could then be rented separately, similar to how people rent by room, but still under one ADU structure.My concern is the permitting process and cost.

The issue you have as you scale is that these are not designed for business use, and if they flag you as a business they will shut you down pretty quickly. 

I'd say scaleable given you curate your designs for each property, and brand it.

As mentioned above Im not sure which listing you want feedback on - but I did notice some typos and design flaws on your site, I recommend going through it with a fine tooth comb. 

I opened it back up today and saw their answer to my question, they just said I could add a credit. 1. that does not solve the problem of it automatically adding inaccurate information, it should instead prompt me to do a security deposit return - so I can add any charges, this seems like basic functionality for a program that is specifically designed for rentals.2. now I can't find the transaction again and can't remember where I found it in the first place (though I do remember it was in a weird place).

My wife is good at interior design and if I didn't have her in my life,  I might hire an expert for that.

It's designed specifically for rental properties, and the process is super straightforward.

Also, how much time do you spend on design?

Hey Gabriel, I haven’t personally used PadSplit, but from what I understand, it’s designed to handle a lot of the day-to-day management for you, which is why it can appeal to out-of-state investors.
