One option I'm considering is adding the equivalent of a camelback, or second story over one side of the home, adding ~900-1000sqft and 2 or 3 bedrooms. 

Option 3: Find a better investment at this time.Stop thinking of yourself as a real estate investor and start thinking of yourself as a well rounded investor.Pay off your mortgage: Your money is not working for you when you spend it on liabilities like a personal residence.Buy Rentals with little/no cash flow: You are speculating what a rental will be worth in 20-30 years.

I want to know the options and you are certainly gave  me good info. 

You can do a trial and see if bank feeds connect, if it does, I would then recommend using it over QBO.One of my client that just started in development is short on funds so Xero was the only best option and they are using a local bank so we couldn't connect and a lot of manual entries. 

Another option you will see online are companies selling shares to sections or lots of trees via a tree plantation management company.  

That would be best option as a traditional bank wouldn’t do this I read that I can assume the existing mortgage.

Have you considered the idea of house hacking as an option?

When I start to post, I don't see "furnished" anywhere as an option for listings.

I'm currently in the option period with it ending on Monday so I need to make an educated decision by then.

There just aren't a lot of options in my area, and my kids need to live close to their dad.
