There have been some upgrades, like the roof, paint, kitchen appliances  etc.Now what gives me concern is that my realtor has a wait for the right buyer to come along strategy.  

Now I can buy one type of paint for all the houses, and some other small things, but having 50 units is 50 separate units. there are just better ways to do things 2a concentrations of geography.

The place needs a new roof, which he will replace, the place needs to be painted, which he will do, there are various and sundry repairs which he will do.

Kitchen and bathroom mostly... little bit of dry wall, cabinets appliances, patch paint, vanity, mirrors countertops.

New carpet, paint, and laminate flooring.

I would abstain of changing carpet or paint.

Here are the options I'm currently booting around while I wait to close.1. sign all tenants who are currently under a month to month with a 3 month lease to let all my funds and the "new owner" feeling settle in with the tenantsa. update common areas like the halls, stairs, paint etc which will give "reason" to the upcoming rent raisesb. at the end of the 3 months raise the rents on those who need it most in hopes of either they leave or if they stay they're paying at least close to avg rents for the area if not the equivalent of the avg rents.c. as they move out update, raise the rents for the next tenants.2. 

I would recommend CertaPro for painting interior and exterior. 

Is this a good criteria to have or is there an easy way to handle the lead paint situation?

Need to get new windows, new water heater, flooring, all paint inside and outside.
