Houston Multi-Family Expenses

[Keith Schuster]

Hi all - I'm looking at a 25 unit property in Houston.  It's in foreclosure and due to be sold in Sept.  I'm trying to run numbers through the Rental Properties Calculator  but I don't have enough information or knowledge to fill in all the expense items.  I was wondering if you all could help me come up with reasonable averages for this type of property - in Houston in particular???

25 units build in 1971.  Supposed to have had new roof done this year.  

I need the following

Cap rate
Water
Sewer
Electric - has laundry
Garbage
Insurance
Other

Vacancy %
% towards repairs and maintenance
% towards cap x
% prop mgt fee

Thanks!

Keith
