Buildium help suggests setting up a bank account and running it with a negative balance. 

Is that a single line dialer or multiline?

Would I need to write a check to my personal bank account and then get a cashier's check once the funds were transferred?

Probably better once they move out and you are accounting for the deposit.I think you have two choices. 

Any ideas how much single family houses in Butler beach can rent for in terms of gross income in a year? 

That transition becomes messy and costly to many investors as they didn't take into account low appraisals, seasoning periods, LTV restrictions, etc...

All monetary accounts had POD or beneficiaries listed (my sister and myself)  We did not want our parents'names to be tarnished by not paying the yearly taxes and their names published in the local paper as not having done so. 

Could be possible for a fix and flip hard money loan for a lender that ventures past single units. 

Otherwise investing in the stock market or better yet, a high interest savings account (mine is at 5.5%) can actually be a safer bet.If you are set on condos, I would be looking in Ventura County.

Should I just buy a single family home(because I presently still rent) and just find other locations for mid term rentals?
