I would recommend sharing your plan with them (so that they can match you with the most relevant loan products), learning about their experience in investing, and asking them what they are fueled by the most in their work.There are many technical questions you can ask, but I find that mortgage lenders are highly regulated in our new housing market (post 2008), so when I'm dealing with the reputable firms in my area I want to focus on getting to know the Loan Officer and understanding if they have the mental skills to help me accomplish my goals. 

I watched Public Figure on Amazon, a documentary about Social Media influencers, and I worry about my 2-year-old daughter and their generation. 

@Aaron MarxHere is a useful mental exercise.

My girlfriend and I are looking to invest in our first house hack within the next year once her daughter finishes this school year.

Old school mentality and I’m two for two on dealerships since I moved, that don’t align with my standards of business (long term business minded vs short term gains) I agree though after having these conversations.

The intent and want has to be self serving and you need to truly look in the mirror and be honest with yourself.Having the abundance mentality is the right mindset.  

The lender's daughter inherited the estate but she too  has passed away.

I've found a duplex at a good price point.I'd have my daughter in one side and rent the other.I want to add her to the title later with rights of survivorship but she will not be on the loan.She would be paying her share but I'm wondering what I will show as my DTI for future multi-family purchases.

Build your network and be ready to pull the trigger (both mentally and financially)Best of luck

@Yonah Weiss I’m thankful for my wife and daughter, for being able to enjoy the most beautiful view of the Sacramento River up here in Redding and for my mom and stepdad who are so supportive and generous to my wife, my daughter and me and the good God that makes it all possible.
