My opinion: if the newbies think they are going to complete deals within a 30 day period, their expectations are awfully optimistic.
It takes time and work to find the deal. It takes 30-60 days, or even more, to close escrow. Once when buying and again when selling.
It takes time to find a qualified buyer-- especially in this market.
There has to be some time for a bit of fix-up or at least cleaning.
To me, an expectation of 6 months to do a simple deal would be a lot more realistic.
To close a deal every 30 days would be very possible, but it would be necessary to get the properties into the pipe line. Each deal finished might be in the pipeline for a few months.
Patience is a valuable asset for a real estate investor. It's a lot easier to pilliage and burn in a hot market. When things are moving slow, buyers aren't buying, and banks aren't lending, things don't move quite as fast.
