Look at their rates and look at their booking calendars.   

I was able to find a few lenders that would be willing to finance the project, but after breaking down the numbers I found that this project will not be feasible given the current interest rates and market rent.

The market here is very strong and competitive- appreciation is at a very high rate at about 5% annually.

When the realtor percentage rates first hit there was a couple posters on there acting a fool.

I dont mean to be blunt here but these all feel like questions that your agent should be giving you guidance on since they know the details of the purchase, the comps, the interest rates, the projections for your investment etc. 

Most of my clients have rates in the 4-7% range, some with interest only.

Are there ones like that specifically rated for stoves?

That won’t work for the summer months on my vacation rental, but it did make me thing about finding some cheap 2/1...

Ahhh.... because it's a reasonable question for reasons that are self-evident, i.e. we want to know success rate of program.

I'm in the position to apply(depending on lender DTI requirement) for conventional financing through the builder at <6% interest rate in this current market.
