@Patricia ChamorroBelow are some tips to find a Local CPA that specializes in real estate1) Attend a Local REIA / Real Estate meetup and see who other investors are using as a CPA2) Network with other investors from your City/State that you find on bigger pockets and see who they use as a CPA3) Look for CPA's with good google/yelp reviews where 'real estate' is mentioned in the review.4) Verify that your CPA is licensed.

BP doesn't allow links but Google "gc license test prep" or something similar and buy a course that serves your state.

Right now one of my tenants has been receiving aid from the state to pay their rent.

You can actually google 'Fannie Mae 1038' and download the form yourself and fill it out based on your 2020 tax returns to see what numbers you come up with. 

@Darren FergusonI would suggest downloading a Storage App to keep track of your receipts(Google Drive, Dropbox, Apple Drive, etc)Best of luck

Google it, and if you can’t find it that way call the local building/legal department. 

Also there can be conflicting answers when googling the str regulations in cities, what is the best way to get a concise answer?

OI also google/youtube all  the time!
