I got a lot of work ahead of me since in order to figure out ARV I also have to figure out market rents (this property ranges from 3 bedroom unit to a studio. 

The cheap ones are positive cash flows...my expensive ones I have now in the 500k range...struggling to cash flow.If i take all equity from 2 or 3 I can probably have a lower payment though for a 500k but my rent I take in will be less then 2 of the cheaper properties...

Prices are extremely strong and inventory low in the range that makes sense for rentals.

Including site prep, GC fees, and construction costs in a normal range?  

Is the range gas or electric?

@Anson Young yeah the front range is so tight.

I frequently get bills from him ranging from 50.00 for a minor fix to $1500 for more major items.

Look at 25 recent closes and 25 listings (if you can't get to 50, don't get discouraged, look at closes first in the price range you are targeting). 

Currently looking at homes in the 150-220k range with a 3br 2 bath minimum.Is it possible to purchase a deal from a wholesaler using conventional financing?

Also considering duplexes (50-75k range) and 4 unit complexes in the Midwest (100k-125k range).
