It's saved me a lot of money unfitting and maintaining rental properties.

Because the units are sub 30k, I am not pressured to take the first applicant with a heart beat.My units are well maintained units with nice paint colors, appliances, washers and dryers (used but nice).I do treat them well and give them the tools they need to be responsible.  

At that age there is certainly plenty to go wrong however, depending on how well maintained it has been up to this point.  

I have a lot of money invested in the stock market, and I'm doing pretty well, but I know the party may be coming to end, so I'm looking at alternatives.  

The seller maintains role as manager of the LLC and invests the sales proceeds in future investments.

Here is a high-level breakdown of the 4-unit property I have been considering:Asking Price: $149,900 Total Rent/Month: $2,135 = $25,620 for the yearExpenses (based on 2015): $12,371Cap Rate: 7.80%Cash ROI: 13.77% NOI: $11,968 Annual Cash Flow: $4,720 (with a mortgage, tax, etc factored in)Property Details:  Four 2-bedroom, 1-bath apartments.Clean and well maintained property.

Therefore, I believe this property will maintain its value if not increase over time.The second property is located at an intersection of a busy, but quiet, highway that has seen development creep its way in a quickened fashioned over the past couple of years, so it is fairly ripe to get.

Good tenants are attracted to maintained properties.The other side of the conversation is on the purchase/acquisition cost.

You might need to buy it for $135,000 to maintain the equity high.

Since you have already sunk the money on these ones, I would suggest keeping them supremely well maintained, and ensuring you get the full lifespan out of them.
