I have seen some decent lots sizes as well to add in an ADU or Carriage Home/mother in law suite. 

I own some property out there as well so happy to point you in the right direction.

I have a good W2 income as well as STR income. 2023 is the first year I thought I could qualify for RE status as I am working as the property manager, handyman... (750+ hours) man I worked hard!

More info is needed but, depending on how much you paid for your current home, buying a a new home and renting your current one may not work too well if the rent doesn't generate cash flow or at least cover the mortgage payment. 

If you’re buying in a desirable neighborhood and have the capital to do fantastic design and furnishing, you will still do very well.

And one room was about 10’x12’ and we still got a dresser and a comfortable chair in that room as well.

You can hire someone to pull local leads for you and you can outsource the direct mail as well. 

Well, just to start, you are the one buying it not them. 

While I agree these are not big issues, in totality, they did not do a great job treating your property well.  

I think you are somewhat off on #4 as well.
