I'm actually located in Illinois. 

The location is in a booming area of McAllen, Tx with almost nowhere else to build and rents have blown up the last few years.  

However, there is a specific deal Which I find hard to understand the ARV for.It is a Single Family Home, 2 Bedroom 1 Bathroom, 850 SQFT.These two comps have a price gap I find hard to understand, even when considering the difference in renovation level.If anyone knows this market well enough to understand the cause of this difference, and if it might be due to an issue with the location, or if there is anything I am missing.Comp 1 - 1011 Elm Street, Burlington, NC, 27217 (120K)Comp 2 - 1109 Walnut Street, Burlington, NC, 27217 (120K)Comp 3 - 1505 N Park Ave, Burlington, NC, 27217 (180K)Thank you!

I doubt we will buy off the MLS but I am trying to find a good way to visualize MLS data so that I can plan our next purchase and get a "steal" that I will have instant equity or rehab for equity with the goal of getting a decent HELOC going.Because real estate values are so location based, it is hard for me to process the data on a spreadsheet, because I'm constantly trying to project it onto a map in mind.To know if what I'm looking at is a deal, I would like to be able to see $/sq.ft. data visualized on a map with either current listings or preferably sold properties.

@Rosette PooleRecommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.Property Class will typically dictate the Class of tenant you get, which greatly IMPACTS rental income stability and property maintenance/damage by tenants.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a property in Class D area to Class A standards, what quality of tenant will you get?

We have many efficincies under management with a ~10% vacancy rate with prices ranging from 485-625 depending on location property quality and amenities.

I don't see an exact location in the OP, but if this is even remotely considered rural, you are adding another LTV reduction.
