Please see the rough numbers below :Tear down house price 350k,Construction cost 165 sqft * 2 build=627k Darnell, did you get your questions answered?

Increased housing inventory as new developments hit the market.2.

Quote from @Roger Flot: I was reviewing some renovated listings in my area and one indicated that even though the house was originally built in 1920, because of all the renovations bringing the house to current code, that you could get 2024 rates on insurance. 

I'm asking because last year I bought an inventory home in Cypress TX that had a $10k discount, however the appraised value of the house came out to be the same as the discounted price :)  

Attend your local REI meet-ups and try to find someone who is currently house-hacking or has house-hacked in the past to learn from their experience.

Every year realtor.com releases a Top Housing Markets report based on anticipated sales growth (inventory) and price growth (appreciation).

I have a confession: my only duplex, which I gave owned now for 2 years and recently moved out of from a house hack, has proven to cost me more to maintain/pay taxes/repair/fix etc to the point where my cash flow is close to zero.

I think some folks search for discounts so that's a way for being promoted.Seems guest dont rent a 4 bedroom house unless they have triple the amount of guests they originally reserved for.  

Ultimately you will have to sell your house at a discount. 

To get started, consider focusing on house hacking in California with properties like duplexes or single-family homes with ADUs, or explore out-of-state rentals in landlord-friendly markets like Ohio or Georgia.
