You will have to file a parentship return.This is not a DIY anymore. 

It includes install/labor. 

If the tenants concern is the basement gets cold then install an insulated door.

Or say a tenant moves out and you have another who wants to move in but has different space requirements and you need to divide the space, or you need to do foundation work to install heavy machines, etc?

Not really a DIY form.

I'd rather do a 1031, can I do this in conjunction with an installment sale?

This is a brief summary of what the property needs:Exterior:remove old roof and replace with new one (Shingles/asphalt)Some serious landscaping (Removing plants, trimming tree branches etc)Partial Painting (Brick/Aluminium siding)New garage doorInterior:Install drywall in the lower level of the house (it's a split level house)PaintingDemo wall between kitchen and living room to make it an open layoutRemodel 2 bathrooms (Tiling, new countertops etc)Panting kitchen cabintes and install hardware, new appliances, tile, and new countertops.Installing carpet on the family room and basementReplace closet/bedroom doors and trimReplacing and installing outlets/switches New water heater Install laminate The total project costs came at 67K (including an 11 % fee or 6,700 the contractor is charging me for running the project).

It's not a difficult DIY project for many installations.
