I'm also interested in multi-family, but have not dipped into that pool yet.I've been assessing my investments, and I feel I need to turn up my real estate investing.  

Tax assessed values extremely low and high rents on all 4 properties, so would not make sense to sell (capital gains) or 1031 (increased property taxes).

Look at the comps in the area, then assess this homes condition and see how much money it will take to get it to sell for what the nicer comps are selling for.After factoring in logical sales price, repairs, holding costs and selling costs you should have an idea of the most you want to spend on the home and still make a worthwhile profit.

If the HOA president sells his lot and ownership of the bulk moves to a new investor, and individual people like myself choose to opt out of "piggybacking," a huge issue could arise: the new investor creates a special assessment on dues and/or sends monthly dues prices through the roof, and we missed our window of opportunity to get out.

So you were very correct in your assessment ... rich dad is trying to  sell 40k programs and the audicance the vast majority could never make it in RE in any way shape or form . 

The city assessor only has the assessed value for the current year, and the upcoming year.  

Actually, you will need to assess your financial situation to determine if your current holdings are sufficient or expansion of portfolio is warranted.I recently listened to podcast 151 and they talked about determining your freedom number, which is what you are referencing.https://www.biggerpockets.com/forums/12/topics/257738-freedom-number (Freedom number + listen to podcast 151)

I found this the other day in Tacoma wa http://www.zillow.com/homedetails/7611-9th-Avenue-...I used the calculator of BP and took my best assessment of the property.

My first deal was very similar I paid considerably less but had I better assessed my number I would have offer $4,000 less.... not much on your first it all adds up.
