I'm considering adding them to even my cheapest rentals because I believe that they are likely to prevent large drain clogs and they are such a nice amenity.

@Kyle Gilbert I agree with the group here...in difficult situations or with combative tenants it may make sense to issue LOI or even a contract with a contingency...so, get in the units you can, get the property secured with a LOI/contract, and then leverage the seller to see every inch of the property before you can remove the contingency and close the deal...It's amazing the lengths some tenants will go to in order to prevent a deal from happening out of fear of the unknown...it's good to have leverage on the seller to assist with getting in the units if they want to sell the property.

It may even prevent them from feeling entitled, as many kids now days seem to feel.

You'll probably also need a back-flow preventer installed.All that being said, If you do replumb interior, pull permits, use PEX and put that in your house description when you sell. 

I messaged cozy support, and they replied below which seems very bad to landlords.Reply from customer service: unfortunately, when it comes to payments being disputed, Cozy does not have the ability to prevent it from happening.

Otherwise, you have an escape to prevent being the next owner of an empty lot.As an avid student of the certificates in Indiana, NEVER buy a property you can't physically visit.

The reason why all of this documentation is required, in a nutshell, is to prevent mortgage fraud and also to prove to the lender that you are in fact a qualified buyer who is able to repay their significant investment into your real estate business.

This prevents them from collecting rent and holding it hostage.You should also ensure you get everything in writing regarding the termination.

I find government will not guide you, they do everything possible to obstruct you, so you need to dig in to what the rules are, you may find out they cant prevent you from making it a duplex, and dont need a zoning change. 

I will say that most property management companies are going to require you to sign a non-compete agreement that may prevent you from practicing management for 1-2 years after you leave the company (within a certain geographic area) and especially while you are working there, so it may be difficult to start your company while working for another company.
