You want to see consistent increases in single family home prices 2%-3%+ per year and household income (over the past decade). 

So there will be a good number of households that will not be able to make the payment required. 

Not sure how big the house is, if there is an HOA or how many in your household so going to make some assumptions and I think there are others answers that are good. 

It will be our primary household, house hacking the property. 

Let's be honest: most of these stuff are needed in every household and I am pretty sure that some of my cleaners occasionally used some items purchased for the properties (I used to have a 3be/2ba house to consume 12 rolls of paper towels within 5 days).

You need to have a long term comprehensive financial plan so that you are always moving toward your long term goal.

(median prices here are ~ 300K), considering rent, I do see folks demanding 2k per month in this area which requires household income of atleast 5-6k (thats 60-70K)..I do believe thats quite high but I am seeing those homes get filled up too...however reducing by 100-150 does't hurt either..In conclusion if musk pays most of the production workers , engineers well (stock being a must here), DV should be OK?

@Robbie Young  Firstly, thank you for taking the time to  respond back with such a comprehensive answer. 

Generally, if there is a shortage, you can apply for the comprehensive permit.  

As far as income requirements, we use total household income which is pretty common.
