My leases allow for month-to-month with both party acquiescence, but I also add a 10% surcharge to the monthly rent for non-lease rentals (i.e. the holdover for a $700 unit is $770 monthly).

This is my first multi unit rental.

I do agree that for all parties a fixed price estimate is best (you need to know how to estimate properly).To be successful as a GC, things like getting a large deposit, making sure you are always staying ahead on billing and are spending clients money and not your own, marking up all costs at least 20% to cover OH&P, billing appropriately for change orders, not to mention staying up to date on latest building methods and continuing education, are the minimum requirements to last in this business.Of course you have to keep construction costs as low as possible when you are rehabbing a real estate project.  

Does anyone know what the going rate is for single family and multi-duplex?

I am not seeing a lot of decent multis but have had some success with SFH on the west side of town.

Can a condo association go after a third party bidder for a Final Judgment of a Foreclosure that the association gained title prior to the bank foreclosing?

I have been looking into some Duplex properties in CA recently and have been noticing that a large number seem to not have  a permit on file with their town or city for the second property that is on the land. I prefe...

I have since been on the lookout for another multi-family, but either the numbers don't work out, price is too high, or my offer gets bested.

Local agencies often miss out-of-state information and those three (Transunion, Experian, and Equifax) are generally considered the most comprehensive and accurate.You don't have to go through them directly, though, many third parties pull their reports.

This time I will concentrate on multi-family apartment property instead of single family houses.
