The guests refused to pay.  

Now, this would obviously be negatively cash flowing since you would need to pay taxes and insurance.

I am the type of person that is normally looking to save a money to increase my investing so the thought of paying someone to do my taxes when we could do them ourselves didn't make sense. 

Things they did bad which I wish I had asked more information about:Never involved in the screening of tenantsThey recommended keys for cash by waiving the rent amount buy only collecting fees which they would get not meThe cost to evict is 750-950 yet other companies told me they will include eviction in the priceThe tenant didnt pay in full last month and I was the one calling out to them and asking questions then a few days later I get an email saying something happened with the tenant and they are investigating.You get passed from person to person every week or so.No one told me when the construction was complete and so the house was ready for a week and the post to zillow and other sites was not done.It took them another week to take pictures and then another week to upload it.I was paying 200 dollar a month electric bills while the house was vacant because they left the AC running in the empty property.

Yes, the government pays the Section 8 rent timely, but more and more tenants are having to pay a portion of their rent.

See if you will have to pay for recapture.  

Quote from @Jarret Jarvis: Hey Will, congrats on paying off your property and your successful stock market investments!

I asked if there was anything else we could try, he got very angry and demanded I pay him in full.

Everything from pay per click, to networking (I've found BNI groups to be a great resource), to cold calling.

They didn't pay for it, so they don't take care of it like an owner.Before you make assumptions about costs based on a seller's contribution to improvements, find out what they improved?
