I have been looking into purchase options, but I might consider a lease option because it wouldn't go against my DTI when I purchase another home. 

Any suggestions on which option should i choose?

Especially going the low down option you will get the best bang for your buck. 

If you're open to less equity, this option would make your home more attractive to buyers depending on your rate.

I would still want to sell as an option in a year or so.

But looks like an option. 

What are your other options for liquidity ?  

I would like the listings to be similar in price across all platforms, but since they won’t be exactly to the dollar, I’d prefer Airbnb and vrbo to be the cheaper option over booking.com.

I'm in Longmont and am curious how/why you landed on that as one of your options.

FHA maybe an option.
