On top of that, the profits seem to be higher due to less costs.

legally, as a cost basis of the house, it should have been included in the closing documents because it impacts things like taxes collected by the state, etc.

I'm just curious...I'm here in CA, and with the cost of housing, I'm always wondering if my home is too large and if I should be finding other ways to invest my money, such as buying rental property (2 town homes instead of a house for example) and moving into a house later. 

Given that many people have said the average price to build in California is $200 and above per square foot, I became worried.Do you think building a 2-bedroom, 1-bathroom home measuring 550 sqft is feasible at this cost?

Rates, closing costs, and points also play a huge role in making the right move and can save you extra.You also want to make sure you have multiple terms like ARM products, Interest Only, No Prepayment penalties, etc.If you want to talk REI feel free to reach out I enjoy helping when ever possible.  

In the meantime, I am trying to better understand the Indianapolis (Fishers, Carmel) real estate market and considering getting a realtors license.In Indiana, the cost for the real estate licensing course is approximately ~$580 and an additional ~$80 annually to maintain.

If so or if you have worked with permits, please provide more details on cost & time line.

As an out of state investor, I made the decision to pull my equity out as construction costs in the area are incredibly high with limited availability right now.I completely agree that luxury rentals would be my prime target for a 1031.
