@Mark SmithWhether you do this as a partnership or form an LLC/Corporation you will need to layout the partnership/shareowner/operating {pick your favourite version} agreement at the outset.  

Than I read different versions of that contract to see what kind of language is being used. 

I would definitely consult with the town building inspector, because every states codes are different ( all based on the same code but some states add or remove, making it there own version) but i'm sure you could use a solid core wood door or a steel plate over a solid wood core ( installing this one in a commercial project in about a week). the closer would be required, but even if you are not required to have a peep hole, you may want to install them, not expensive and it gives your tenants a sense of comfort. 

Most banks have some version of buy-rehab. 

I swear, I hated the old version.

Maybe tenants ought to send in their version of the rental agreement. 

You can also find a real estate attorney in your local REIA and they can give you the 5 or 10 minute version of how it works for your state.Sharon

We listen to tenants but try to not take sides or play referee.To get a good starting version of a lease/agreement that meets the tenant landlord or your state, I'd join a local property owners association.  

The post was since deleted by BP, so you will have to click the small dropdown next to the link on google to view the cashed version. 

A friend of mine is a software developer and is offering to create a CRM system for me to get rid of my primitive DIY excel version.
