Hi , everyone  how many  5% conventional  loan or fha loan  can I have at a time  for multi units  property  on "primary residence " and  how  can i use this strategy  to scale  ,i.e buying  property  every year to aquire more. 

If you give them a shorter term lease, do it at a higher rent as you are going to be inconvenienced trying to find a new tenant at what may be a hard time of year.

One was at their six month time limit...like a day or two before. 

S**t happens in life but you still honor your committments.
