Borrow more money on my property? or get a new Loan?

[Pedro Jimenez]

I have a Property worth about 110K in Dallas TX,  I owe 60K.   I financed with private lender at 9% interest because I could not qualify for a loan 6 years ago, now I might qualify, my credit score is in the low 700s I make about 60K a year but my credit history is only 2 years old.  I currently own another house that is vacant because I do not have the capital to fix...My question is; If I'm trying to qualify for a traditional mortgage for a 3rd house and also trying to fix my vacant house, should I go back to my private lender who would lend me an extra 20K and charge 4K to do this.  The lender would then ad the 24K to the note (at 9%)...  Or is that money too expensive?  Should I look for other type of financing? 

 if anybody can point me in the right direction please
