I have a Homeowners 101 certificate.

The property rented under a two-year lease for $900 a month.The property inspection turned up pretty clean, just a few items like pushing insulation back into place or removing some pending inspection/certification labels.  

Would a Realtor with a CDPE certification qualify to negotiate a short?

I grew up in Michigan in a family owned property development business working  tradesman roles such as brick and block mason tendor, concrete form and finish, rough and finish carpentry, sheetrock hang tape and float, electrician in both Michigan and Georgia, plumbing, and HVAC gaining my EPA certification.

I allow a well-trained family dog, with the following requirements:  $1500 security deposit instead of $1000 security without a pet, AKC Good Citizen Certificate, vet records showing age (not a puppy), breed (no restricted or mix with restricted breeds), current vaccinations, current license, and renter's insurance with minimum $100K liability with me listed as additional insured.  

When you create a statement from your company that authorizes a member or owner or officer or designated other person to perform a duty(ies) or function(s) of your business, this statement usually needs to be signed by someone who is identified in your Articles of Organization (or Certificate of Organization – whatever it is called in the state of origin) as an authorized person.

I just joined Bigger Pockets to learn more about tax lien certificates, tax deeds, low or no money down financing, buying and holding, flipping properties, wholesaling, and possibly starting a business later on.

Once the Certificate of title (in FL) or Sheriff's Deed or Trustee's Deed (name depending on state) is recorded and the parties of interest (lien holders) are notified, you will be on the hook. 

I am also currently enrolled in the Commercial Real Estate certificate program through UW to learn more about financing, development, etc. of commercial real estate.Overall, my plan is to acquire long term buy and hold residential and/or commercial properties in core areas or emerging corridors.I am excited to get more involved in the real estate community.
