I've heard some rumors of Airdna skewing data a bit (I've heard this first hand and read online.)

The great thing about living in a high cost of living area is that your salary / wages are hopefully also very high.If you are a new college grad, I would focus the next 1-3 years on increasing your salary as much as possible(gain new skills, new certifications, change employers, etc).Once you make more money, you can easily get in a position to buy a property on a more frequent basis.Best of luck!

My point is for you to read my response. 

@Stacey OlsonRecommend 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.

Thinks that basically read to don't use C4D to F-people. 

Wow, you are firing off questions faster then I can read them and they are all good, but pretty general.

please send me a case example I'd love to read. that's one appraisal. the knowledge I have as a licensed general contractor working with investors from 5 cities at a time all over the country buidling 3 different floorplans I would say trumps one ADU you read about online 

Sejin - Have you read your fair share of books as well as listen to podcasts?

Go search the topic "Lifestyle Asset University" here on Bigger Pockets and you will see a longer thread with a lot of opinions (most are not members) but still worth a read as there are a half a dozen paid members from our group who have commented on that thread.We were formerly called Lifestyle Asset University, but I didn't realize that you couldn't use the word University in your company name here in Utah so we changed our name to Vodyssey. 

Also when you are under contract and get condo docs, make sure to read the meeting minutes (for the past year if available) they will indicate if there are any talks of an upcoming special assessment (which you don't want).
