To me, that's a LOT of money to pay.

Pay no attention to the keyboard warriors that took a course from a guru that's really not been around the block.

We had a backyard pool decommissioned, (concrete broken up around the pool and dumped into the pool along with several truck loads of waste hauled out and dirt brought in.

@Renee JonesSounds like you need hard moneyA hard money lender could fund this but recognize they won’t pay a contractor upfront they will only pay when portions of the work are completed.

Just make an offer, explain that as investor that is what you can afford to pay and let them decide what to do next.

You should never allow a seller to become a tenant; he will be able to delay eviction YEARS, not months if he doesn’t pay.  

@Bob Mai wow, interesting how biased your post is.Their 4% is only if you PREPAY their fees for 12 months, otherwise 6% monthly.They have a minimum of $75/month, which means if your property rents for less than ($75/6%) $1250/month, you will pay more than 6%.They use Latchel for maintenance issues - Latchel is not cheap and there's a kickback in there somewhere.There's a list of extra fees for extra services and there's a lot they do not handle.You get what you pay for, so good luck.

Is the squatter some random person or where they living there at one point and stopped paying rent? 

How much do you pay for drywall guys to repair a wall or ceiling?

You can also, "pay for keys." you would say something like "hey if you leave in 10 days, I will give you $500 dollars, but I have to see all of your stuff out and nothing destroyed to the property."
