Also, I personally wouldnt cash out refi right now just because the interest rates are high but thats just my opinion and it really just depends on the numbers if you want to make a calculated decision. 

So much so that it would be difficult to make even a dent in the need by opening thousands of homes.When done right, these are high cash flowing homes.

My main concern is GETTING financing for it since we have a high debt to income ratio. 

Any way around paying the very high property tax, school tax etc. in SC?  

But 1k a month in utilities definitely seems high.

Is NOTHING sells for a refi appraisal price  I  mean nothing that appraisal is always high.. so when folks say hey I got a refi and it appraised at this and I now have this much equity that is also not true and wishful thinking..

.: Quote from @Tim Delaney: That seems odd to me assuming you aren’t in a highly negative cash flow situation.

Be sure to take high-quality photos, and if possible, request utility records that confirm separate billing for four units.

@Maegan Quaife, Of the 4 prongs of the Internal Rate of return 2 of them are very high for you - cash flow and amortization of the loan. 

That's not to say you can't do well there, but I'd encourage you to look at Belton and Temple (which can also be very rough and block to block) rather than Killeen.The good news is that there continues to be serious population and job growth in the area.
