.- I go to military training on the 7th.I have a good lock on my interest rate and afraid of doing the mortgage application over again due to a slight decrease in my current job pay but will be going up again in a few months and I'll also be house hacking once I own and solely live in the house.

You would have lot of negotiation later on with buyer.If discount is substantial I am not afraid buying home with roof issue or lien, that's easy to solve when you have the cash.

I'm so afraid to underestimate costs.

Additionally, I'm not afraid of starting the business and building from the ground up. 

Connect with other investors, build your network, and don’t be afraid to ask questions.

If you just told them to pay, they may have been afraid to tell you they couldn't as opposed to asking questions where they know you want honest responses.

I'm all about having strong opinionated people and surrounding yourself with those who are smarter than yourself and who are not afraid to tell you the truth.I would like to obtain and move into a 3rd property(townhome) in a nice neighborhood.

Don't be afraid to negotiate, particularly if you have a lot of rentals.4.

Biggest thing I learned from my first house hack was to not be afraid of repairs.

I'm afraid we would have raised entitled little brats of little character and limited drive to succeed for any other reason than to create an opulent lifestyle for themselves, practically blind to their enormous privileges, just like most every other moderately financially-successful couple we know socially.Thank you all for your insightful contributions here.
