I used to do contractor work and we would always inform the customer of their options.

Exhaust all of your conventional or government financing options before you get into DSCR. 

The options are:1. you could get it from investors but then you will need to use an SEC exemption2.

I would first check to see if HELOC is even an option - in TX its hard to find and can only be done for a primary residence.

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.

That gives you options to expand, hold, or sell land if the income isn't there. 

I figured what better place than the bigger pockets forum to ask if maybe I'm not thinking of all my options.

But there are options for interest only first five years. 

Closing Costs – Remember to factor in refi fees and how long you plan to hold the property to determine if refinancing will save you money overall.Since you mentioned owning the property for only a year, your equity might still be limited, impacting your options or leading to higher costs.
