should this be my first deal?

[Adam McCarty]

I am looking at this deal that includes 2 six plexes and 1 five plex.  It will be one closing and they all share a parking lot.  These are old houses that have been converted into apartments.  My biggest question marks are maitaince and capex.  I have figure them high thinking worst case.  My biggest concern here is that they are boiler heated house.  I havent had any experience with these and dont know what the cost might be.  the two 6 units share a boiler that looked 10-20 years old and the 5 unit has a brand new tank less system.  Also i will be self managing but have put in management for analysis.  Any feed back would be great.
