How do you close your own deal by paying off dues?

[Vijaianand Thirunageswaram]

I am trying to find the unknown part when trying to close the cash deal yourself. I always use title to close the deals but if the deal is small enough compared to the title cost, I was told to close myself. I am working with a wholesaler on a lot sale which is really few thousands dollars whereas title cost almost 75% of the deal. I tried to see anyway to cut the cost and some suggested to close the cash deal myself including Seth from retipster.com.

I never don't it so I started researching with helpo wholesaler. We got most covered including getting title search done, standard Deed template, erecord title etc., Now only missing part is, is there a service to find the Tax and HOA dues like getting Tax Certificate and pay them off as well to clear the title which is done by Title companies.  I was told you can just buy it and pay it off afterwards or do we pay them first and by mail or in person?  

Anyone every close their deals? I posted in the PRO forum but not many responses so opening up to everyone.
