I've got a property I own free and clear but I'm having trouble getting financing for to do the repairs due to the fact that I'm self-employed.

Long story short, the repairs took over 10 months to complete.

Hi there,  recently bought a couple properties that need some repairs.   

Have to repair or replace fence in back yard.

If I am only going to wholesale the property to another investor as soon as I buy it, do I have to have the exact repair costs or a repair estimate?

I would caution against what @Timothy Lewman is saying about it being a "colossal waste of time" to look at these properties ahead of time.

We've spent about $1k with our existing property management company on repairs in the past few months, but their in-house repair team did not address the issue.Right now we have a trust issue. 

Even the LADWP is a pain to deal with and anything electric can linger for months if not years in this cityFor that reason, i would recommend to absolutely avoid any interaction with the city unless you do really heavy work that would have significant impact on the appraisal like maybe adding bedrooms and bathrooms or adding lots of square feetThe current system doesn't reward doing the things by the book; you actually will be way ahead doing things on your own and just comply if you get an order to comply one day (very unlikely anyway).

I have the money for repairs but would like to get into the property with no or low money down.

It's certainly fine to run your break even analysis on rent/repairs and market rent comparisons.
