So to outline an example let's say you have 2 partners Joe and Frank.

The rule clarifies that the LLC’s membership must be limited to family, sets forth the application process for the exemption and notes that the exemption is not applicable to engage in conduct that loan originators are otherwise prohibited from engaging in as outlined in ORS 86A.224 and 86A.236.

The issue I outlined with last sale can apply to any of these criteria, and will vary a lot by county.

Make sure you have a lease, outline rules, responsibilities, expectations.

Recently, a friend from church told me he was planning on buying a duplex and outlined the basic house hack to me. 

If I actually knew you I would give you a 2 hour outline of my best methods to grab an easy deal, set you on your way, and tell you to call me if you ever needed me. 

This is very common in the CRE world (usually using Limited Partnerships), and Single Asset Entities or Single Purpose Entities (you'll see SAE or SPE thrown around a lot) are the only way to insulate your deals from each other.Depending on what type of deals you do (flips or buy/hold/rent) you may be able to have the actual dollars flow through the operating company, just creating a paper P&L for the asset level entity.Again, I'm not an attorney, but have seen this done in the CRE world, and its the rough outline I follow for my investments.

The lease didn't outline details, so I want to be mindful of how things are worded.

Make sure they outline the scope of work, for example, electrical, plumbing, structure, cosmetics, etc.

There's no need to go in front of the ZBA for a variance. http://www.phila.gov/li/Pages/Zoning.aspxYou may already be grandfathered in, check the Zoning Archive to see if one of the previous owners filed a use registration permit outlining use as a two family:http://www.phila.gov/zoningarchive/
