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

But there are options for interest only first five years. 

I see a couple of interesting options on Loopnet.

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

That being said, there is probably more to this story and therefore other options. 

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.

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

Quote from @Stevan Stojakovic: Given that your property isn’t a primary residence, a cash-out refinance is likely your best option to access equity.

Many investors switch over to these loans once they have a few properties (typically 5 on average, but you are right there in the typical fashion for property number 4)Check out these series of articles on the loan topic published on BP as well for all you need to know about this option!

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