1. Be sure you want to live at the property in question.
2. Read and understand the lease before signing.
3. Document the condition of the rental unit noting any flaws in the condition of anything, and any repairs needed with photos and in writing, before moving in.
4. Get a Realtor to help you and answer your questions, in person, so you don't have to rely on strangers on a website to get answers. I know someone who can help with that...contact me for details.
