Is it possible that lenders may start looking for a way to free up funds that are tied up in low-interest loans such as the ones that are being issued now?  

In property, having too much cash tied up, simply kills investment returns.Now - we are not talking about "too much leverage".  

However, I really thought the metal trim would tie in the stainless steel of our sink, faucet, and future appliances. 

I worked with a partner 50:50 who had much more experience but multiple contractor issues, health issues to my partner, and high crime in the area lead to most of my capital being tied up for 9 months with no profit to speak of. 

However, If I were in your shoes, (and wanted to keep the tenant in place) I would simply give a 30 day notice of a change of terms to your "verbal" agreement. 

The landlord is locked in and so is the tenant, until either court action is brought by landlord or a mutual lease termination is signed by all parties.I'm sure the landlord in this case is ready to move on but her hands are tied until this is resolved.And why should she just fold and not recoup some type of compensation for removing the unit from market.

If I were in your shoes, I would be very wary of anyone through BiggerPockets that reaches out to you and tries to sell you something with a better ROI. 

Kim Forgione Banks have their own internal process for cleaning the title and then getting a property ready for sale.Any number of reasons can tie up a property in legal issues like other claims to the property or a previous owner declaring bankruptcy.And the bank will also hold off moving inventory until they feel like it’s the right time to put it on the market.

Although I have little cash on hand (most tied up in my business), I do have a lot of experience in rehab/remodeling.

I assume so because you mentioned a lakehouse.I use crimp connections for all my PEX work (except when I have to tie into existing copper), and have not had one fail yet.
