Wholesale with problem tenant

[William Klawitter]

Hi all,

I'm working with a seller whose main motivation to sell is that his ex is living in the property. She doesn't have a lease, she isn't paying rent & he wants her out- but he'll likely need to evict her and is afraid she'll trash his place in the process.  

I think I can turn this into a wholesale or wholetail (the place is in pretty good condition, no major repairs) if I can convince the seller that selling off market to me is the easiest/safest solution. So my questions are:

1. What are my main selling points? Why am I a better option than either a) him just listing the property with her in place, or b) him just evicting her & hoping for the best?

2. What's the best approach from my end in terms of acquiring the property & handling the tenant? Cash for keys & then wholesale? Wholesale with the tenant in place? Wholetail (take title, evict/cash for keys, then list)?

Never dealt with this situation before, so any input is appreciated.  Thanks in advance!
