To make the house amazing we need to enlarge the windows and take out a few walls to make it open concept.

The whole concept of house hacking is to try to eliminate the expense that otherwise would have been used for rent.

Existing of a simlar platform is actually a good thing which implies that there is a proof of concept in some form or shape.If you are curious enough, I am open for a short chat

Then there is the concept of opportunity costs from lost of capital or lack of cash flow.My personal business model was to achieve FIRE quickly through real estate.

If the tenant ever moves out just know that second generation restaurants are very valuable because a new restaurant owner can come in with very little capital and get their concept going.

The wall between the kitchen and dining room was removed to make for an open concept living area on the main floor.

Re-directing tax funds to "affordable housing" is a very nebulous concept, short on specifics, and likely to not move the needle.  

I think you're right to the concept above not being a great concept.

The 30 year fixed rate loan would be a better fit for this purpose.You might be able to think of some other scenarios but hopefully this concept is good enough to know the difference between the two. 

Timing matters more than knowledge.Serious, how hard is it to understand down payment, mortgage, buy a house , rent it out.You're right, the general concepts are pretty easy to get but the devil's in the details.
