If you have some time, I recommend that you read a few books before hopping into anything:1) The Book on Flipping Houses by J Scott2) The Book on Estimating Rehab Costs by J Scott3) The Book on Investing in Real Estate With No (and Low) Money Down by Brandon TurnerThese 3 books should give you a solid foundation to start your journey.

Typically in my area the water seepage Is between the footing and the foundation wall.  

I just finished installing one on permanent foundation on a private lot.

So I need a whole bunch of work done to my soon to be house hack , the list is as such but not limited to in order of priority : -Roof for house and garage - siding - all windows and window frames - kitchen and bathroom reno in 2nd unit - fix minor foundation cracks - upgrading all electrical outlets in 2nd unit - gas fired boiler will need to be replaced but can last maybe another year or two without replacing if serviced - water heater will need be to be replaced soon - appliances for 2nd unit - leveling the hallway of the 2nd unit - painting the foundation and the 2nd unit - both units currently have a styrofoam ceiling which makes the units look smaller than they are , but this will only be if I have enough money left over .

I will check into foundation...Thanks!

If you wanted to start now I'd convince your parents/ guardians to set up a custodial account with Schwab or another brokerage you can research and invest in real estate stocks such as Invitation Homes, Lennar, American homes for rent, Zillow etc. 

Then network with people who have already achieved what you want in life, and when your financial foundation is set, take action and buy a home.

Did he give you the foundation for free?

I truly believe that with enough grit and perseverance anyone can find success assuming they have put in the work to build a strong foundation through education.Of all the challenges you’ve faced, what setback led you closest to the verge of quitting and how did you overcome it?

Remember, you are in hurricane country and wind and rain blow horizontally so check to see if the roof has been properly repaired and that there isn't any slippage in the foundation.
