We've done a lot of multi-unit buildings over the years and it actually goes more quickly than you might think. Once you establish the similarities it's easy to get into a pattern.

Overall, organization is key. Make a good map and have a good system for keeping the units separate. Usually, their addresses or numbers is the most logical thing to do.

My biggest problem is staying focused as the time goes on. The repetition is unlike doing a standard house and it's easy to double inspect and area or, worse, miss an area. It's imperative that you go through each one in the exact same manner so you stay organized.

I've also found that the only part you need people to be with you for is the inside of the units. Hopefully, you have some access to the property to get a jump start for mapping and doing some exterior work. You can also always finish up the exteriors and grounds afterwards. One potential problem is if you catch something outside and want to get another peek inside.

Try not to let anyone drag you off course... there is always at least one tenant, usually more, that has some special circumstance and has to have their unit inspected at a certain time. The property managers and agents also have a tendancy to want to tell you how you're going to do things.

Establish who's in charge right up front or it's a nightmare. And I don't mean you have to be mean.... just explain that in order to do a good job you must have access when and where you need it.

Overall, big jobs like that are pretty good money and I've never had a callback on an apartment or multi-plex. The repetition is really the only downside.

Good luckk!
