I have noticed that as companies they grow, their quality and attentiveness tend to decrease. 

You also need UX, support, quality, a million other things.

This is where you can significantly increase the value of the property by making improvements that attract quality tenants and justify a higher rental price.

(Assuming quality of service doesn’t decrease.)No matter how you look at it, that is a ton of money.

and you will have many many applicants assuming the quality of the rental and the rents requested.  

@Rory DarcyRecommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.Property Class will typically dictate the Class of tenant you get, which greatly IMPACTS rental income stability and property maintenance/damage by tenants.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a property in Class D area to Class A standards, what quality of tenant will you get?

If you need to get it rented fast, a great property manager would list the home for $2100 (below market) and get several quality applicants competing against each other to drive the price up to the max so you don't risk vacancy by starting out too high and gradually reducing to find the sweet spot.

As you already know, the quality of the investor agent will speed up your learning curve, and save you money, time, and headaches. 

Since you're not rushing for a quick flip, you can focus on quality construction, tenant-friendly designs, and strong rental markets that yield solid cash flow and appreciation over time.A few things to consider: Location is key.

Perhaps a better vetting of the buyers on the BP side will enable better quality leads?
