As a first-time homebuyer & house hacker - I need all the tips! 

Hi Tyler, I would recommend coming to @Dan Webers monthly meetup in Portland where there are many house hackers and more experienced landlords who can help you through your journey!

I am a local agent and former house hacker.

We're curious what other house hackers or investors think about this.

You may want to attend, we get plenty of guest from NYC most of us are house hackers or looking to house hack.  

Utilize your son as the house hacker to teach him about real estate investing (maybe even having him help with management), and get the low down payment and low interest rate.

You would have to change it to one lease where everyone is accountable, but most property managers won't even do that.Since more house hackers are doing rent by the room strategy, I'd imagine we might see a few property managers willing to take it up in the near future, but I'd imagine they will probably charge 15-20% PM fee for managing it due to the more work, liability, and lease-ups that will result from rent by the room strategy.

In general, Fannie Mae and FHA (included FHA here for you house hackers) both really frown on debt with deferred or teaser payments, be they student loans, credit cards, or a new car.The way you would use this credit card trick combined with traditional mortgage financing is to have a very well laid out plan to get in the door using hard money + CC, and in X months have the CC debt down to zero (or in payment, with a due amount showing up in a bill each month), as well as having the needed PITI reserves. 

This has been a great resource for me and for others.Should you need anything, I'm a 2x house hacker, agent, and OOS investor.
