Any possible solutions (aside from just fixing everything immediately or asking for a massive price reduction)?

Is there a managing company on green renewable energy on cheap/free land or water, selling electricity per kWh and selling carbon credits, leveraging preferential rate financing and tax reduction for green energy ? 

I can assure you, I would have those tenants out as quickly as possible, then I could complete my inspections and either accept the sales price, negotiate repairs or a price reduction, or walk away from the deal.

So, if interest rates are a buyer’s primary roadblock, then I recommend seeking opportunities to negotiate a rate buydown at a seller’s expense or looking at new construction, where builders are offering rate reductions and other substantial incentives.What if I’m a seller?

While the percentage of homes with price reductions increased from 12.7% in May of last year to 16.6% this year, the overall share of inventory is lower than in 2018 (17.4%).

Make sure that your lender has copies of all amendments to the agreement if you agree to a different sales price or concessions/reductions are made.

If the numbers say you should pull out, then pull out or ask for a price reduction.  

On top of it, reaching 20% down through principal reduction and appreciation could be a decade out.So you should probably look at the project as a long-term partnership with you co-owning this with your sister for the foreseeable future.But these are great opportunities. 

We've found little blue fentanyl pills (extremly addictive and deadly) in cracks in the floors and in "out of reach" places they had fallen.

But back to the original point. on RF today 99 homes have price reductions and about 2/3 are above the median of 550K, yes 'values' will drop if the price is initially set too high, which this the data tells me.
