Hi Michael,I like your thoughts of building a large portfolio because it's very important in sub $100,000 markets like Ohio.A large portfolio = A safe portfolio.Personally, I've always been a big believer in buying with cash.Less is more.Once you gain experience and understanding the true income vs expenses of your portfolio.Then look at using leverage for faster growth.It takes many years to learn a market along with establishing a solid understanding of it's "in's and out's" from a people/team perspective.As investors we should always reverse engineer and protect the bottom line first and foremost before looking toward expansion and growth.My "cash only" mentality has served me well over the years in my businesses and real estate endeavors.Especially when things turned South and they always eventually do.Start slow, start small, buy with cash and build from there.Just my opinion and wishing you much successps.
