Cold Caller. real estate

My house acquisition strategy is bassed on the "Slow Flip" method as conceived by Scott Jelinek It consists of finding and buying houses in blue collar areas that need some work, and then selling them on an installment plan to contract buyers on a thirty-year contract. The houses are financed by investors, who get a return on their mnoney: typically on a 5-year term. I get my leads for houses from four sources: direct mail, the MLS, Zillow/Redfin/Trulia, Faccebook Marketplace, and Craigslist. I need an assistant who can (1) Evaluate each lead to see if it fits the slow flip model
(2) Contact the owner or broker to aks questions and establish rapport
(3) Make offers, either with owner financing or cash.
(4) Get documents ready for closing.
A friendly and helpful demeanor would be a good quality to have for this job. The job requires some general knowledge of houses: electricity, gas/forced air heating, roofing, etc. Also helpful is some knowlege of how typical real esate transactions are conducted in the US
