@Dan Chandler I wouldn't take condos off your list but there are some due diligence items you should consider that are not necessarily part of a SFR due diligence list1.

First off, you should have gotten quotes for all the items BEFORE you closed escrow, why waste all that time!

He has not abandoned the property if significant personal items still remain.

Then you can address those items as well.  

2) Imply big ticket repair items?

Most the time this isn't even an itemized task that a dollar amount is put too.

The purchase agreement should layout a time frame to complete some of these "due diligence" items.You will need a boundary survey and title commitment to verify there are no liens or encumberances on the property.You will want to hire a geotechnical engineer to verify the soil is suitable for building an apartment building.You will need an environmental engineer to make sure there are no contaminants (asbestos, mercury, lead, etc.) on the site, as well as wetlands and/or endagered speices.If you need to rezone the property we may want to consult an attorney and/or civil engineer to help with that.Depending on how many units you intend to build the city may require a traffic study be completed to determine the impacts to the streets and intersections.This is typically how we start a new site and it is a very general list of items.

When you hover-over a dashboard item the drop-down list appears.

Old Newspaper, not only because he might burn up if anyone tosses a match but because he is quite out of date.Next item: investing in equities outside of real estate.  

We'll need to get linens, kitchenware and some smaller ticket items, but luckily, it should look fairly like the pics for a while.
