To be honest, I'm not sure.  

Honestly, it really comes down to finding the right bank.

So your number of 715k may not be too far off depending on the square footage and also the age of the cabin.For anybody to suggest otherwise without knowing more information on your specific cabin isn't giving you the best advice to be honest. 

I understand there is a lot more that goes into this process but I'm just curious if it makes sense from the most basic viewpoint for starters, thanks for your input! 

It’s possible but honestly, there is no benefit to doing a portfolio unless you have too, typically LTV’s are lower and rates are higher.Many pros to doing them separately rather than bundled.

Always good to check before you cash out the 30-35k, which I honestly would not do with the drastic change in PITI, numbers would be tight even if you rent out the unit you are currently staying in.

Their practices are neither transparent nor honest, and I would not recommend their services to anyone.I have money owed to me and they have not sent an ACH even though they have my routing information.

Quote from @Himateja Madala: @JD Martin I was hoping to get a good deal in the buyers market but honestly it is beyond scary to get in right now.

If you can hold on till first part of January the showings and everything else should pickup.This would be my action items: 1. hire a new agent that can sell the place, and get you numbers are rent and selling and sell the place. 2. be honest on the numbers you can get on an ARV so that you can sell it 3. start to get the conversation started with a couple lenders on what these numbers on refi would look like for you and this property 4. my suggestion would be to refi/rent before selling at a loss because if numbers work you can hold for a couple years then sell, but this is dependent on your cash position and liquidity of your situation.
