I have a basic knowledge of real estate 2 home purchases/rahabs (NM & CA) and 1 sale in CA.

I know there are quite a few what if's, but again a basic start to finish process on paper.  

Ideas such as what are  Very focused certificates or training that young people can do in order to get a base income very quickly. 

Once you get a basic understanding of the concepts, make sure you have a team who can support you and then hit the phones! 

I have a quadplex it has a basement we roughed in to add a unit one day....well, we're thinking it's "one day". 

The same thing applies when renovating a basement and adding bedrooms/sqft. 

Adding a kitchenette could run $8K–$20K, while a basic bathroom might cost $10K–$25K, depending on plumbing proximity.

I recommend everyone always create their own IRR calculator as they can get pretty complex and oyu will want to understand all the inputs and outputs. we provide a basic one to those in our membership group but I always recommend build your own and understand not only the numbers but sensitivity that lines up with those inputs.If you are hard money lending thats simple as its just a column of dates and amounts for loan provided and monthly interest and points.

Many investors have used this strategy successfully, whether by renting out extra rooms, a basement unit, or a duplex/triplex.

You don't need to know everything to get started; you need a foundation to build on, and the rest will come through experience and then refining your education.You can build a basic understanding of investing in 3-6 months.
