I want to further expand my knowledge because I dont understand much of real estate terms, taxes, and everything in between. 

@Jason Allen a wise question, but there's no specific industry standards in the SFR area, like there is for MFR.Read below for what we use:Recommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.When investing in areas they don’t really know, investors should research the different property Class submarkets.

The general understanding throughout the industry is that 2 tax reporting years meets this qualified use rule.

The irs might argue that the 1 acre build site is worth twice as much, the other 9 are just standard value.

Commercial brokers understand that seller financing, either as a first lien on property the seller owns free and clear, or as a second or wrap, can be necessary to conclude a sale.  

I understand that the age and quality of the home will impact when these expenses become due, but I'm curious if I could get somebody in the Austin area to take a look at the estimates I put in here: https://docs.google.com/spreadsheets/d/1jgP6aod25qWJzKWQXhto...

ROI gives me everything I need and I understand the process.

The industry standard remains at 2 1/4 inches.

Also, make sure you read through and understand their warranty process.

For commercial the gold standard designation is CCIM, so once you get licensed start working on that.
