Quote from @Katie Nolan: Here's the Oregon Landlord - Tenant Law: https://www.oregonlegislature.gov/bills_laws/ors/ors090.htmlHere's a handbook that may be easier to understand: https://oregonlawhelp.org/resources/landlord-tenant-law-oreg...If you're going to be successful, particularly in a heavily regulated state, then I recommend you study the law regularly.

Study up on FIRPTA. 

Have you done a cost segregation study on any of your properties?

A cost segregation study would be more beneficial this year. 

I dont know anything about which of them put the money up or if it was some fraction from both and don't intend to try to study that out. 

They will help you ensure you don’t accidentally leave money on the table by helping you study your competition and by raising or lowering your rates so you can compete better.

The problems are with the inexperienced under capitalized people studying wholesaling strategies as put forth by a variety of guru/mentors and the temptation these people feel when they smell a profit.   

Most aren't in class, studying, etc then.

A cash flow study should be performed to ensure that the refinance does not drastically reduce the property's return.Good luck!

That means taking your time to study what you want to do (in this case what type of investing you are most interested in) and speak to those who have done it successfully.
