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

Also Solo 401k could be a better option for you if you're self employed with no FT W2 employees.   

The property is rented out for $3,200 per month, while my mortgage is $2,100, and the HOA fee is $268.I explored the option of taking out a second 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.

It just obviously won't be market specific.On a personal rezoning I did for a house hack new-construction triplex, I was asked numerous questions about how many bushes and trees I was going to plant.

Other than Regus there are very few options. 

You can always do it with your own IRAs, however your employer's 401(k) may or may not have such an option.

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. 

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