New Mexico investors

[Larrian Davis]

Hello Everyone,  Im running my numbers on properties and falling into the negative in cash flow. I believe it is due to rent being so low and mortgage high. I m looking in northeast heights area in New Mexico. For an estimate in your area how much are the rent prices? I wonder if maybe my calculation is wrong rentometer estimate average is the wrong number I should be using.  

Also, is there a quicker way to run numbers before doing the 4 square method ?

Thanks so much in advance!
