Because I did not buy this on Biggerpockets, am I not able to access the bonus content.

I talked to Padsplit and they manage SFHs renting each room to different tenants - the total rent is more than renting it out to one household.

Of course, I totally understand that you wouldn't want to do if that guide is written by another real estate agency, in which case you have option 2.b.

IE - 70% of total units are rented at levels <=80% AMI.The higher your “Mission Driven %” (IE - the more units you have rented at levels <=80% AMI) the lower your interest rate will be.

All my properties (11 total) are in Detroit, Memphis and Seattle and if you want to chat about any of those markets, happy to do so. 

This was a total win for me!

The loan on this house is $1,200,000.I moved in to my new primary residence by the end of the month.Starting July, my original primary residence was available as a rental and was being shown to prospective tenants.My new tenants signed a lease that began a couple weeks after showing, in July.To calculate my primary residence mortgage interest deductions, i'm using the following formula:650,000 / 2 = $325000 loan from January to June1,200,000 / 2 = $600,000 loan from July to December$750,000 limit / (600,000+325000 total loan value)  = 0.81 multiplier(0.81 * $X first house interest) + (0.81 * $Y second house) = total interest payed i can deduct from my primary residencedoes this look correct?

Everyone's 401K rules are a little different but the way it works for most is you can borrow up to $50K or half the total balance, which ever number is smaller. 

I have done some research on using OPM as well.I first began learning about Wholesaling and studied a bunch of content over Youtube University where I came across BP. 

Typically, I also avoid paid education because there is so much free content.
