I'm not what you call "experienced," but here are some basic rules.
a) keep the property for a minimum of five years
b) make sure the mortgage payments will not be a handicap when the property is vacant
c) owning property means also upkeep expenses *make sure the wiring, pipes, water heater, heater and ac, and roof are in good order, and no termites
d) buy on highland over lowland if it rains alot
e) make sure you have time to "manage" the property
f) yes, take it slow
I sold our income property when I retired.
