I have scoured multiple sources for opportunities, but haven’t found much.

@Jenny Gremillion Other good topics to discuss with your CPA: (1) intend to turn them both into vacation rentals and hold onto them, or (2) installment sale (owner-financing).

I don't know that this helps with direction and I think there was a gap in looking at opportunity costs when making decisions. 

If you have a $100,000 loan at 3.75% and that goes up to 5.25% but your able to get another 50-100k out the additional cost on your current loan is only $1500 per year which is a small price to pay to go create some other opportunity that over the life of that second investment can yield you $50,000-$150,000.My biz partner told me years back, "Don't step over quarters to pick up pennies", which to me most of the time translates to calculate the money you are not making by taking that next step vs the money you are trying to save.

On the one hand, this is a good thing, as we have the opportunity to turn over those vacant units and rent them out at market rates.

I feel like that would be undercutting them by taking away their opportunity for a percentage of the deal.

Yes, the house may rent for $1400 and cost 200k, but are there other opportunities to get more rental income out of the property?

I’m fuzzy on my intended down-payment here, but to me, the most important thing is that the numbers work.
