I suggest you wait until late winter to sell.

The focus should be on eliminating vacancy and avoiding chasing unreasonable rental rates, especially in the slower winter months.Here’s a chart showing the median sales price of a single-family home in the City of Austin this year through November:The median sales price for a single-family home in November 2024 was up roughly 8% from the beginning of the year.

You make revenue here and there but the goal is to generate enough in the winter to sustain all the expenses for the entire year. 

You will have to rewrite the contract.

Also control the thermostats so the tenants don't jack up the heat in the winter giving you a massive bill.

And, would that invalidate the contract?

Land Contract.

If there was no contract/business/transaction between tenant and deed owner can deed owner still be sued?

The cancelation contract stated they would refund my deposits in 6 months or if another buyer bought the contract for the properties. 

It's usually better to earn $200 less a month for one year than to sit vacant for two months, particularly in the winter.Consider a bigger drop for a 6-month lease to get through winter, then increase rent or find a new renter in the spring when competition is hotter.
