Hopefully, second child's college education Lessons learned?

My long term goal is to invest heavily in RE (Buy & Hold) over the next 5-7 years so I can retire comfortably. 

Sale price will be a little below market value with a Home Style loan (4% down), rehabbing ($80K-$100K) mom's home into a place my family and I can live in (better schools, bigger yard, and other benefits) comfortably with a growing family.We plan to renovate the attic of our current home and make some cosmetic repairs ($60,000 HELOC) that take it from a 3 berooom 1+ half bath to a 6 bedroom 1+half bath with a separate 1 bedroom apartment that has a livingroom and kitchen (apartment is already renovated).We then plan to rent the Air BnB for 2 years and re-finance for equity and leverage to buy more rentals.

As far as a next purchase or a savings, I personally prefer having a certain amount of liquid assets to feel comfortable, but also think that aggressive investing is what gets people ahead fast.

Convince a partner that you are willing to put in a large amount of the funds needs so they feel comfortable. 

The rental income should cover the mortgage which is great but if I found something where it didnt cover it in full but my family was comfortable I would still be open to it.

The money will run out way before you can retire comfortably with cash-flow. 

It sounds cool to house hack but you can keep staying where you are now and rent also the 3rd master bedroom, I assume you pay less than $1500 for a 1 to 3 bedroom now, so by staying where you are now you can cash flow positive and stay in a comfortable non roommates situation.

@Jacob Phillips - I try to keep three months of expenses for ALL my expenses (business, all rentals, personal, etc) but aim transition to 6-months emergency fund over the next year (we just had a second baby).Given you have only one rental, I would be much more comfortable with 6 months expenses and at least 3 months personal expenses.

As i was looking for my first deal I felt comfortable working with someone I new.
