Suggest you go the electric route--less or  no maintenance costs, and when repair is needed, inexpensive compared to most gas fired boilers or furnaces.I would also have a small natural gas wall space heater installed somewhere on the main living floor (not in bedrooms) just in case of power outage and / or for supplemental heating.  

I aim to know more about the park than anyone.  

Wouldn’t supplemental insurance cover anything else that Airbnb’s insurance doesn’t cover?

Aiming for young adults ages 22-30yrs old.

Are you looking to create financial freedom on investing, or is this just a supplement to a holistic retirement strategy?

During 2009 when I bought my condo in SF, to supplement my vacation income, I signed up with a company called Air BnB to rent out my place when I was gone.  

I supplement the costs of all these repairs with my day-job salary, otherwise this would all be over a long time ago.

Taxes are Around $1500/2000 (aiming high), just based on our homes we currently own.

Paul,...If you're going to wholesale like a professional, only pursue deals that are worth Cash Buyers' time (target for 60% ARV if you're not confident about estimating repairs)Some wholesalers aim to lock up as many houses as possible and then walk away when their 2 cash buyers won't buy [bad] deals.

My goals aren't fully defined yet (working on that soon) but in the short term I hope to bring in enough passive income in the next 3-4 years that we can supplement my wife's salary giving her more freedom and flexibility as we look to start a family.
