Most counties have a chart that allows you to figure out these amounts.2) 20% for PM, Vacancy & MNT?

Included in 10% MNT

Of course, there are other investors that post they have their own setups to handle what you're asking for.Suggest you look into MNT services like Task Easy, Task Rabbit, Porch, etc.

Here's an answer with as much thought:Pay cash for a property you can rent out for ($15k+ tax, ins & mnt)/month!

You also only have 5% for CapEx and 5% for MNT, total 10%, and we usually recommend 15-20% for Class C.You'll also want to be careful with the property taxes!

You'll find many posts here on BP that recommend only 5% for MNT Reserve.But that 5% won't work on lower class properties.We recommend:Class B - 10%Class C - 20%

The HOA is 127.50 a month (lower than most HOA's in this area) and it covers Exterior Mnt of Unit; Roof Repair; Roof Replacement; Blanket Ins Policy; Garbage Collection; Common Area Maint; Street Maint.

You're supposed to figure out your annual NET INCOME:Gross Rents - Property Taxes - Insurance - Property Management - Estimates for Mnt & Vacancy = Net Operating Income (NOI)NOI / Value = Cap Rate

I have a good RE attorney in Black Mnt (20 min down 40 east) if needed.

But maybe unlike other places, Snellville was surrounded by Lithonia and Stone Mnt/Clarkston which is an area dominated by class C and D homes.
