I'll have to run the numbers on the comparison of 15% vs 20%  Rehab costs of $25,000 And add in $2,500 for each of the 2 closing costs ( so $5,000 total ), and I'm right there at the TOTAL amount needed of $40,000 to get this property.I have just over $40,000 of Equity in my Primary .

That's before you get into the fact that MF, IMHO, is work/a job in comparison to my business model.All in ALL, I am seriously looking at NOTES.  

ARV on my house is about $200K right now as a comparison.

My grandfather has lived in the home with my late grandmother for the past 30 years and is still currently living there but never held title to the home, so I'm not sure if that makes any difference in regards to how he will be taxed on the proceeds in comparison with his son whom has NOT lived in the home for 2 of the last 5 years.

I bought them both in 2019, so it's not a fair comparison to today's market -- especially if you're comparing in Greenville where the $ amount of housing prices has jumped much more.  

I'm sure it will be about min.wage(not 15$/hr) when after looking at comparisons for the next 2 units.

So what changed that allowed you to buy 33 properties in 3 years in comparison to the initial 3 rentals?

The person would do comparison shopping on Lowes, Home Depot, Amazon to find best price for me. 

Pre-qualificationIf you are too "Poor" to buy what you want in a neighborhood you are comfortable in, look at 1st time housing grants to increase your down payment amount so you can buy more house.The amount of the loan, and the amount of your down payment + grant will dictate a particular MAX purchase price for you.Be sure to allow for closing cost and loan costs in your calculations.Once you have that MAX dollar amount you can spend start looking at what you can afford in different neighborhoods.For instance in some cities you might find a Class D neighborhood 4 plex in good shape for the same price as a Class B neighborhood duplex.The Class D place might give you more cash flow than the Class B too, [BUT]Maybe your chance of getting robbed or shot or carjacked in the Class D neighborhood might be greater than the Class B neighborhood (so factor things like that in too).The question is still which should you buy--First whittle it down to specific properties the Bank will let you Afford--then make an apples to Oranges comparison as best you can.

@Jordan Moorhead I do not own properties in that area but the most profitable are small apartments like 2/1, 1/1 or studios since are cheap in comparison with bigger apartments or condos.
