A couple hundred for your time is fine but some charge way too much.Markups on maintenance just encourage maintenance and make the pm more likely to agree to repairs or upgrades when they aren’t needed.  

Since purchasing we have made some minor cosmetic and logistical upgrades.

I'll be upgrading my 1st rental property and selling it.

People move to upgrade their living situation or relocate.

Ha, yup, brutal honesty is best.Although, both of those sites could use a makeover/upgrade, especially Chandler Reports, it's currently allowing for insecure logins.A part of me wonders if building a similar, smaller tool (more focussed reporting) for next to nothing to use....might be worth it, as it would connect me with many investors.

Due to the number of plugs and spaces available on the panel it would require a panel upgrade as well.

I'm looking to upgrade without breaking the bank.

It also gives you an opportunity to do minor upgrades when you need to replace something over that 5 years without them losing their "resale" value.

I am considering buying a house in my home state (which is Pennsylvania) living in it for about a year and upgrading it (not sure how much the upgrade is going to be, I don’t even have the house yet!

I would focus on ugly / smelly that you can fix in 2-3 weeks Max (paint, flooring, maybe upgrade kitchen or bathrooms) and get sweat equity from that differential (and a little less competition from move-in ready homebuyers).
