Depending on local market conditions you may well be better off buying homes that are on the market or even foreclosures BUT before you do any of that you MUST look for a multi housing association, landlord group , landlord association in your state , join it, make use of any seminars they offer as well as all the materials they have available to members because if you have not had rental units before you may want o learn all you can first so you can try to avoid many of the mistakes many LLs do actually make and learn the hard way from.
