Some takeaways from him:Treasury Regulations section 1.280A-2(i)(3) gives a couple of ways you can proportion the rental portion of a property--my accountant used square footage.Under section 280A of the tax code, common areas that you also use are considered part of your personal space and unfortunately aren’t counted as part of the rental space in the proportion calculation.

Meaning you must have an appraisal completed and the lender will look at the 1007/Rent schedule and use the lesser of the "Common rents" of the neighborhood or the current rents of the property.

As an aspiring real estate investor, avoiding common mistakes is key to your success.

This is a very common issue in commercial/private money space.

And you can combine different exchanges from different owners as long as each exchanger is purchasing a tenant in common % of the new property that is at least as much as they sold.But you cannot 1031 a primary residence. 

So I do have some personal experience with affluenza, and I'm curious to see how the folks on this website are avoiding this common outcome.

I came across multiple colleagues of mine lamenting the lack of clarity on this common issue. 

So folks who press on cash flow and to a point that it's the only thing that matters--commonly miss the forest for the trees. 

The only work involved is if the so-called realtor lied or posted the wrong info. this is very common many brokers myself included have minimum fee's of 5 to 10k..
