If you work legal notices, tax delinquencies, and out of town owners, you will have more leads than you can handle.

Since the condo association is the one insured, should they handle the hiring of contractors to gut existing sheetrock, and put up new sheetrock? 

Also not sure if your condo has many requirements for tenant approval and abiding by rules for any short term rental so do you find it be relatively simple to handle from another state?

Both let you wrap the rehab costs into the loan, reducing what you will pay out of pocket. 

You definitely need a title/escrow company to handle the transaction.

Any recommendations for good Attorney in Portland, OR  to handle this?
