However, there are some small breeds that love to dig, scratch doors, chew trim, dig on carpet, crap everywhere, etc. 

Moen = crap

Richie Sr.I would definitely raise the rent, and not bother with the fridge until it craps out or falls apart.

I have 2 plans on how I can acquire this property, and I need help in figuring out which course of action I should take, or if both are them are crap and if there is a better way of doing this.Plan 1: I negotiate with him on taking over his mortgage and pay him the lump sum he is asking for with the remaining balance.

I think it’s a combination of jump in and learn things by trial and error, checking YouTube if you need help, and being around people doing it.  

That would probably be the best wait case for me but I spoke with one commercial lender before I made the purchase and he said they would do a combination approach so they would be looking at some more buildings was my understanding

THe frameless are more time consuming to put together but are great looking, plywood and not mdf crap like Ikea.

Could be any combination of the above scenarios.

However the grandmother insisted that the crap outside was my dogs and I needed to pick it up instead of talking to me she spent a little girl over to have her tell me to "clean my dog s*** up".

With your point made, I'd most likely have to work out either a higher than usual lease option fee, get the ok from the owner for any rehab done or a combination of both when negotiation with prospective sellers.
