Has everything been e-mail? Do you have rental applications? Run credit reports. Have a record of showings. Newspaper ads. The more support the better in whatever form. Craigslist is good, but it isn't necessarily the only/best method. The key is can you justify that with the right tenant you were ready and WILLING to rent.
Regarding the expenditures, electical and window appear to be capital expenditures. Brick work and "minor stuff" expenses. Painting, depends on why. Probably expense unless it was to complete a remodeling/construction project.
Hi Richard -
Based on your replies, the property was placed in service in 2010.
If you make improvements to a personal residence, the improvements are capitalized, but not depreciated (your basis increases). If rented, the improvements can be depreciated. (In this scenario, a portion of the cost of painting may be related to the electrical upgrade)
As a comment, you can also depreciate the building. Your basis for depreciation is the LESSER of your original cost plus prior improvements or current fair market value. Your basis must be allocated between land and building.
