We have subsequently bought more personal and pure rentals. 

I know that a duplex is more likely to have more frequent turnovers, and the subsequent leasing fee of 1 months rent (I have decided to use a PM that charges these fees), and the associated repair fees before a new tenant moves in.

I've found that if I don't get good vibes from someone it's usually because of something that is subsequently uncovered during the screening process.  

S, broker-in-charge of a sole proprietorship, listed a foreclosure property, the sale of which would earn a selling agent a bonus of $1,800 plus full commission, and subsequently presented an offer to purchase to the seller from buyers whom she had represented in approximately five or six previous transactions, listing herself as seller sub-agent on the contract.

That subsequently KILLED my confidence in the beginning.

After all expenses my NOI is between $13,000 and $14,000 in the first year, with it charting upwards in each subsequent year.

When the home was subsequently heated & ready to inspect the appliances were run again & water leaked everywhere & each appliance required new components. 

Subsequent appraisal afterwords confirmed my original CMA was correct.

Can't wait to hear more from you and about your subsequent successes.

Then if I find that it is so simple i can do it myself or it's not worth the money, I'll do it myself on the subsequent times.
