One of the funds I buy from does this quite regularly. 

I am trying to determine reasonable cleaning prices to go with a checklist for a tenant who has been served notice.

Im regularly looking at houses but some help would be great. 

Do I just get regular home-owners insurance, or is there a special type of insurance I get instead of home-owners insurance?

Personally I wouldn't pay for an inspection until I knew that the seller could close with a clean title.

Same goes for the surveillance cameras as well.What really is problematic is that no matter how much you try to tell people NOT to FLUSH down things like diapers that will cause the sewers to back up, it ALWAYS happen... and, according to my Contractor.... there is no worse job than to clean up that mess.So.... correct some of these that lead to over-consumption, high maintenance costs, etc. and you may get a better, more affordable housing situation.I don't think it's a large percentage of the people that are the problem.

., significant rehab budget, title is not clean, etc..)?

After a plumbing, AC, a giant dead 200+ year old oak tree removal, and the “good” tenant leaving 6 weeks of repair and cleaning work, we had to unload the property.

And lastly , Maybe consider partnering up with local wholesalers and consider 18% return before rehab( and yes those can still be found) , and find a hard money lender that might lend you 80% and 100% Rehab, . 1 year lend and then refinance and get Regular loan , I know you might have to pay the Interest and might take a cut, but is the name of the game, and luckily you might get to 10 to 12%.. 

Staged homes spend half the time on the market compared to non-staged homes and they regularly sell for about 6% above the listed price.
