BIG Investment Opportunity! 64 rentals

[Khyler Holderbaum]

Have the opportunity to purchase 64 homes, all have renters, book of business is very profitable. 90% of the properties have new roofs. There is a full time caretaker hired for 35K a year. Comes with lawn care equipment. Maintenance guy has his electrical license and plumbing license. Seems like a great deal, located in Ashland KY. Guy is wanting me throw out an offer first. Cheapest rent is 600$ a month, to 1,200 a month. What are my purchasing options? At 60K a house that puts me at a 3.84 million dollar loan. 25% down is 960,000. Any thoughts? Should I offer this guy a 5 year plan to help him save on capital gains? Owner finance? Just a lot of variables and am relatively new to the industry. 

Thanks!
