Just from reading some of the discussions and posts, I am proud to be such a wonderful community of individuals helping one another.

This four unit home welcomes families and individuals to a 3bedroom 1 bath, two 1 bedroom 1 bath and a studio apartment with a full bathroom.

@Jeffrey Trudeau No those properties are on separate parcels of land with their individual tax id.

It includes all major assets & liabs, inc some pers prop that has value (or is individually insured) & I would consider selling to fund new found opportunities or if there was a major emergency requiring a change in budgeting/liquidity.My PBS is currently three pages long, broken into sections w/ sub totals to assist in analysis:AssetsReal Prop (Assessed, Purchase/Rent data, 2-3 free online providers like Redfin, then averaged.)Personal Property (Cars, Art, Hard Assets, things not in an account or "foggy" daily market value)Cash Accounts (ie funds w/ access not limited by age, Banks, Brokerages, CVLI, prepaid taxes,large pending incomes like insurance settlements & reimbursements owed to me.)MineSpouseCo-AccountsRetirement Accounts (or anything where access to the value is age restricted)MineSpouseBusiness 1 (Net number carried over from separate business records)Business 2 (List as needed)Liabilities (Would section these out too if I had enough to justify it)Listed in order of assets above if tied to such, mortgages, HELOC, etc.General liabilities listed next, largest to smallest.Net Worth CalculationThen I include several lines of totals; subtotal of amount available for conversion to REI, ratios & simple measures like mo / mo & trailing 12 mo avg % & $ return.My FI goal is over the long term to average at least 1% mo / mo gain in net worth.I have found this to be best for me for several reasons:I have a hard time visualizing a set $ amount as a goal because my amount required to retire would then seem too big to tackle.

Let me address your concerns individually...1. 

Tax treatment gets a little complicated when two individuals buy a multi-unit property and one of them occupies a unit. 

Pragmatically what happens is you expand the Fannie cap to 20 by putting each property/loan only in one spouses name (we can thank feminism for that, once upon a time women didn't have individual credit, only EITHER joint with their dad or joint with their husband).

(Disclaimer:  for those of us who have no sense of humor, this was an attempt at humor and no way should be construed as being in any way discriminatory.)According to the article:"It doesn’t apply to sex offenders or people who have a criminal conviction that, after an “individualized assessment,” shows that denial based on the conviction “is necessary to protect against a demonstrable risk to personal safety and/or property of others affected by the transaction.”You'll have to obey your local laws, and do an 'individualized assessment'. 

My intent is to rent individual rooms.

I bought my place after the last financial meltdown, so I have plenty of equity to cash flow my house as a rental and I thought about it last year, or an equity split with a friend to get him into being a home owner; but then you have to look at Cash on Equity instead of just cash on cash returns as I have heard David Greene talk about before (just looked it up to make sure and it is in his book http://biggerpockets.com/longdistancebook).I found a facebook video of David talking about the long distance thing, which you have probably heard on the podcasts (probably won't be able to post the link to fb: https://www.facebook.com/BiggerPockets/videos/newest-biggerpockets-author-david-greene-talking-long-distance-real-estate-inves/10155417628854833/)
