I have been approached by a couple of wholesalers that I found on Craigslist in Southern California.A few questions:1.

Wether this discussion is a basic formula or your own success story on what you've done, I'm trying to get an idea of what my best approach is to grow the fastest. 

I'm not familiar with the program you mentioned so I don't know what it offers above the current DYI approach.

Non sure what the best way to approach this would be so I'm asking for your advice.  

You could still do a modified or slower approach to BRRRR by looking for value add multi's that need economic and/or physical upgrade that you can do as tenants turn over and improve the quality and value of the property over a year or two but still with ongoing rent/cash flow. 

Another approach is when someone gives notice that they are moving, financially incent them to allow showings and behave during showings by offering cash if the place gets rented to someone else while they still live there.

@Steve Vaughan  I'm not sure if this was the best approach to get out of a rotten deal however I assigned the land contract over $0.00 fee and had the end buyer sign a mutual release agreement that releases liability on all aspects of the property and gave him the rights to my Land Contract and mine has been dissolved.    

AFAIK, I would need to procure a commerical real estate loan but getting this with no experience is unlikely.ThanksMatt

If they have an asking price, my offer on their asking price is the best offer.I approached a real estate agent about a month ago on an advertised apartment building (8 units) with an asking price and "owner willing to finance" advertised.

The valuation of the property and appraisal will be a little bit more on the income approach in my experience.
