Here are some ballpark costs to consider:Assuming you could build 1 duplex per 1 acre - you would need the following:a) Boundary survey + Topo survey = ~$3.5k per duplex/acreb) Civil Engineering design set for each duplex which includes house placement on land, drainage, septic design = $7-8k per duplex/acrec) Septic system + install =~$20k per duplex/acreHope this helps.

That's because tons of people tired of living in a cardboard box for $2,000 a month and are quickly getting the hell out of dodge:http://www.mercurynews.com/2017/01/03/its-a-fact-the-bay-area-rental-market-has-softened/http://www.mercurynews.com/2016/10/24/bay-area-rents-are-falling-new-survey-shows/http://www.siliconbeat.com/2016/10/24/bay-area-rents-falling-falling-falling/?

This data comes directly for the most recent american community survey and is representative of the data collected for the census tract that most closely approximates the Mayfair neighborhood boundaries. 

If you surveyed real estate agents, the greater percentage would prefer exclusivity.

I was actually planning to go to Volkswagon for the next one before I started questioning my car strategy.In an era of cell phones, the easy availability of Lyft/Uber, and a AAA-plus tow-anywhere-within-a-150-mile-radius membership for $85 per year, the logical reasons behind owning your nice truck and paying all the expenses associated with it aren't anywhere near as logical as they used to be.

Idk about you but I can use that $20K towards the purchase of an investment property. the MLM game isn't for everyone and many are already tapped out of their newness so there isn't any more room to make the type of money that they state so many others have done. the whole thing boils down to recruiting others and that's the only way for you to make money. you'd have to get a good handful of people to sign up for $20K membership each and really think about it...if you come across a handful of people with $20,000 to invest, wouldn't you rather that monies go towards a project of yours?

I have a Rentometer Pro membership to know my rental rates.

I would do a thorough risk management survey of your property. 

I've been to MAREIA a few times and actually have membership with them.

I think i would cancel my membership.
