I just want to make sure I don’t make a mistake by listing it without having anything in writing.

I won't say you will never make the same mistake again but I'd bet money on any of your next deals you don't make this mistake again.  

@Terry LandonEven if someone give you a referral, what meets their expectations, may not meet yours.In our experience, the #1 mistake owners make when selecting a Property Management Company (PMC) is ASSUMING instead of CONFIRMING.It's often a case of not doing enough research, as they don't know what they don't know!

"Since you’ve offered the $300.00, honor it"That I believe is a mistake, they burned that offer when they got greedy.

The sliders are still generally solid wood outer frames and the worst the tenants can do is knock it off the track or damage the plastic guide on the floor, which is cheap to replace.

Don't expect an independent to give you the best quote, just because they give you seven quotes doesn't mean they are not the seven worst you could have been quoted. 

The biggest mistake people make when attempting to invest overseas is trying to apply US strategies overseas.

You can hear real-world examples of how others have built their investment portfolio and (hopefully) learn to avoid their mistakes.4.

It was a good option for me as I made the mistake of having too many primary mortgages that made my DTI look really bad as I didn't have long term(2+ years) of rental income on my tax returns.

@Christopher TeagueRecommend exploring as many sources as possible to get referrals AND cross-reference them to get as much accurate information as possible.Check out NARPM.com, BP’s Property Manager Finder (BiggerPockets: The Real Estate Investing Social Network), etc.Also, encourage you to learn from the mistakes of others - by reading posts here on BiggerPockets about owners not having their expectations met by their current Property Management Company.
