@Toby FellowsYou are correct, you need to ‘hang’ your license under a broker in order to practice real estate, and most brokerages require you to become a member of the National Association of Realtors as well.While you are preparing and taking your courses, contact several brokers and interview them to find out who might be a good fit.

You are absolutely correct.

Things like this are why it's important to work with a professional who is well versed in real estate taxation because the "common/simple" strategies taught frequently like BRRR or house hacking actually get fairly complicated when it comes to handling it correctly. 

Leverage, when used correctly, is one of the most effective ways to scale.

Drew and Simon are correct.

I had to search it myself and call listing agent who edited the correct listed property and not mine :)Also, if you are getting random "I heard you were selling your house" calls and texts, they are usually wholesalers trying to get you to consider selling even if you're not.

@James Hamling is correct about those cap expenses coming. 

You are correct they handle by PM company liability I have prudential personal liability.OK, yeah, and they (Coterie) doesn't offer commercial umbrella insurance (or personal) so I was concerned you might not be covered correctly.You have a personal liability umbrella through Prudential?  

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?

If that’s correct, here’s my non-expert opinion.
