Two potential solutions I have in my mind are:1.

I don't have the room to add a Washer and Dryer, so I'm trying to come up with a solution that I can offer.

Here's the solution-- go find the realtor(s) that have worked that very area in the last 3 years.

Even with a shared bathroom and living room, your place is likely much nicer than the average extend-stay motel, so if your rents are competitive, then you can likely serve this avatar.You may find that a 5/2 is an acceptable temporary housing solution for a family displaced after an insurable loss (fire, flood, etc.).

@Andrew Grimmett If a seller is hesitant due to capital gains taxes, consider creative solutions: suggest an installment sale (seller financing) to spread tax liability over time, a 1031 exchange to defer taxes by reinvesting in another property, or a structured sale for flexible deferred payments.

I'm thinking that repairing the plumbing leaks and getting the soil dried out could be a permanent solution.   

A better solution, in my opinion, is not to rely on wholesalers,  as not only is it a dying breed due to the sheer incompetence they exhibit due to gurus' wrong instructions and teachings, but, wouldn't it be better to generate your own leads through a high performing website?

I really don't want the liability, but is there any other solution?

Likely your best solution is to do a 1031 exchange. 

This signals that this is my final offer.Focus on win-win solutions.
