I should be a little better at getting through the contract and the other detail tasks.

Zillow Offers (home owners, buyers and investors to estimate property values quickly) 3.

I do not have my numbers as well organized as @Greg Scott but my estimate is upper 20% annual return on average.The 3 i am currently invested in, one seems likely to produce an outstanding return (High risk, high reward), one is conservative and is performing to projections, and one i have significant concerns about but has not had a capital call.  

The key is to understand the capital stack, who is in line in front of you and what are their terms.The people who are getting burned may have known there was debt in front of them, but did they know it was short term or variable - did they know all the details to make a good judgment on the investment.If a property had 20 year fixed debt at 70% would you take that over 3 year debt on a variable rate at 50%?

There is much confusion about the 4% and 6% in property taxes.Non owner occupied property is taxed at 6% of the value to get the taxable value.This does NOT mean your actual property tax is 6% of the purchase price for rental property,In reality property taxes are about 2% of the purchase price for rental properties and about 1% of the purchase price for owner occupied properties.Google Greenville County Property Tax estimator and play with it and get a sense of how it works.3.

I will hire a local person for emergencies and other stuff but wondering if anyone on this forum had specific details.

I attached rough estimate on here, I included rehab on to the sales price 

Would you mind sharing any details about your townhouse?

I'd estimate you'd need to rent it for $1,900.
