This is not an issue I would spend too much time on if the property looks like its still standing and has no obvious red flags.3) Refer back to item 1.4) Yeah, you'll have to evict them unless you want them as tenants (I don't recommend).

And second, be sure to not only assess repairs immediatley necessary, but also look at your capex items for the next years (5, 10,.. depending on how long you want to hold the property).

Figure out what you value in life and do stuff every day that align with those items (for extended periods of time). 

Try your best to estimate the costs to fix each item (do your homework, ask here).

i suggest taking it step by step and incorporate these items as you gain small successes going forward. 

Good answers above on some of the big items.

Yes it was my grandpas house but that’s related to the items that were in it.

Suggest you get hold of a licensed general contractor to itemize the deficiencies in the order of urgency and your budget.

Find ways to improve these areas, a new paint job and some articles and items to create a "theme" in the bathroom can go a long way and make it much more enticing.

I truly Am appreciative to each of you So no one has leases with something like tenant is responsible for maintenance items up to x amount
