Yes, you will have to pay taxes back for the depreciation amounts should you sell in the future. 

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?

My initial plan had been to do something like Rent-to-Retirement or REI Nation- assuming that I'd be leaving money on the table to pay for their expertise, but hoping that I would learn through the process and develop the confidence to strike out on my own later. 

It starts with doing 10-20% of the work and paying much lower taxes.

Using mortgage debt at 6-7% on a refinance to pay off higher rate debt such as a credit card at 15-25% is a savings!

I’d simply ask in what situations where the broker and the brokers firm did nothing to facilitate the sale do you think you should get paid a commission?

We take care of the entire process—from sourcing and purchasing properties to managing renovations and the final sale or rental.

Of course the solo would also pay the notes.

My knowledge is free, but I am most happy to charge for it, if someone is willing to pay!  

That's less than anyone's paying in rent.
