Help I need to bump rents $ 200

[Steven Maduro]

Hello bigger pockets family

I have a problem 

My areas rents have increased far past my own mentality In assessing the values

I have properties in Decatur Ga

Zillow and rent ometer say that I should be charging 900-1300 on one property that I am renting for 700

And 900-1100 on a property that I am renting for 800

The props are in pretty good condition

Newly painted interiors some renovations done fair amount of amenities hot tub in the 800 prop

 Washer dryer in one 

And w/d hookups in he other 

I was thinking of going section 8

Although there are several things that scare me about that 

but I am willing to give it a try

All of my five units seem to be well below market by he others are about 100 below market each

So how do I raise the rents?

Get a prop manager to run and manage them since they seem to be able to maximize value?

Evict this crop of tenants and re rent at market rate?

It just seems like increasing rent by 200 on one tenant is just unfair 

But I have to do something 

I am

Losing thousands every year because of this
