Funding Whoa = Cash to Go??

[Chase London]

I need some advice from a Pro or 2 or 3. I tried getting funding from a lender to purchase my 1st 4 unit property but the loan but the loan officer's lender sent me a denial letter. After speaking with the officer afterwards he stated he's gonna use a different lender just give him a little time. Now going into week three i'm ready to just say screw them and use cash.

Im seeing fixer uppers in my area in the 4k-10k range. I know they need work but I have a family of carpenter/plumbers etc including my father. Im thinking about buying one to move into and stop renting and save the cash to buy the multi-unit and not bother with lending.

Has anyone been there done that? any advice
