Doing it yourself will work, but it takes education, time, and effort to achieve success.

I got plans and a permit to legally add it to the sqft.

I saw a notice on the door from the city and I tried to get some info on the owner but it looks like an investment company has owned it for several years but no one has been in there.

I personally never look at BP on my phone or the app on my phone but i just checked it and its still there it brings up the forum threads maybe BC I already had it ? 

It’s overkill but it’s much cheaper and easier to use. 

If you're willing to put in the work, you'll obviously make more money without hiring someone to do it for you.

Do you ask for it or do they just pay but they think it’s worth?  

It took several months.

I’d keep it, do a little cash out refinance if you wanted to regain some of the $, and just rent it out or STR it and make some money on it..Appreciation always goes up, and a few years down the line (and/if interest rates come back down you could pull even more $ out Tax free!)

It will change.
