Interest rates on 30 year mortgages have dropped .75% to 1.00% in the last week!!  NOW is the time to buy.  These are historical low rates.   Based on our experience, rents generally lag anywhere from 9 - 18 months behind rates, so invest now to lock in these great rates and lock in your cash flow.  Often, single family rental rates never adjust downward to reflect the reduced interest rates.  Single family rental rates have generally moved up in good times and just stayed flat during bad times.  Interestingly, we are seeing rents increase because so many people are unable to buy so demand for these properties has increased.
