My husband and I are planning to invest in 5-10 rental properties over the next 1-10 years, including a mountain vacation rental, and I am debating getting my CO broker's license while I am unemployed.

There will much debate on this point, but I don't see the market pressures easing up in Seattle for 7 more years, and that's only because I'm not comfortable speculating to that degree.  

I've served on my boards ethics committee, and there is great debate about whether you can divulge the price of other offers.  

If that is what you are saying the CMA versus BPO debate doesn't really matter.What matters is that you use a broker/agent who owns investment property themselves and knows how to estimate for repairs and cash flow model things out for your holding time.Of course you verify their numbers yourself.  

such as 15k offered on a 25k asking price. its basically giving them a guaranteed closing and a quick one at that. guaranteeing their carrying costs to soon be ending, among other benefits that the bank may view from this, at least in my opinion...yes there is an actual property that i am debating on doing this with, and those are the numbers

Here's what I gleaned as a summary of hardening tips for reducing turnover/maintenance costs:panasonic bath fans with timers in bathrooms4 coats of poly on wood floorsdouble door stopstile floors, showers vs surroundssingle lever shower valve vs. doublereplace toilets with steel parts/mechanicals whenever it starts to runKwikset smart keys (some debate over efficacy)door stoppers on all hingesremove pop-up drains and replace with commercial drains2' drain lines from sinks with an accessible clean outbuy a key cutter - maker for $50 on craigslistGranite tile counters - need a diamond polisher and tile sawUsed Fixed vs. friction shower rodsKeyed deadbolt and passage knob on outside doors to prevent accidental lockout5/8' fire core drywall - can't put a fist thru it and its fire-resistant1/4" board to back up towel rodspolyurethane cabinets under sink to pre seal and drain water to the floor2x4 base under cabinets to prevent particle board cabinets from failing where they meet the floorVinyl scrap under sink and up the back wallBest of luck!

I'm debating whether or not to sell my home and upgrade to a larger home.I purchased my current home as a forclosure in 2011 for $63k.

As someone who has gone through the same debate (whether to get a formal inspection or not), go get one.

I agree, the "plus" side as it were does seem debatable for those already receiving a premium, enjoying 5 star reviews, etc. 

There's a lot of debate as to whether or not investors should or need a license.
