If you do the deal, ensure you have your property taxes set aside, because with seller financing there is not an impound process to handle the taxes and insurance. 

There is a lot to consider before you buy your first property.  

My first property is in Warner Robins GA.

Similarly, if you put several Class D tenants in a Class A 4-plex, what do you think will happen to the property?

So your capital gain when you sell this property will be calculate against your tax basis and not against your mortgage as many investors expect.

We don't directly manage properties.

I previously owned rental property but sold them and am now looking to get back into real estate investing.

I'd keep an eye on ancillary properties that become available. 

Generally - the depreciation on the structure, mortgage interest, property taxes, repairs & maintenance, insurance, property manager, utilities, vehicle expenses (mileage), professional fees (reports/CPA), home office (office supplies, percentage of utilities, continuing education).

These properties require more capital up front, but can really help your overall real estate portfolio.
