Establish a local network of trusted professionals, such as a handyman, plumber, electrician, and a local real estate attorney who can address urgent issues promptly.

I am trying to find a reputable realtor / agent who will help me place tenants, but also be able to help with semi-annual / annual walkthroughs (for a fee of course).

I was wondering if anyone could provide a recommendation for a reputable property management company in Northern NJ that handles small multifamily? 

Seems like there are plenty but hard to tell which ones are reputable.

My best advice would be to to look at quality sponsors that have a track record to back their reputations.

Thanks Hi Karolina, I meant to comment on your previous mixed use post, provided 50%+ residential and 85% occupancy should be several reputable lenders that can provide workable terms. 

Hi Carlo,In each of my locations (FL, IN & CO), it was slightly different...in Indiana, where I'm originally from, I asked friends and family for their suggestions on plumbers, painters, handyman, etc.

This is true but 1) the problems in LA has extends beyond the city's core and 2) the city's core is essential for the city's reputation, which in LA has nosedived which will make it harder to lure in new companies or even keep ones there which are considering moving.

Ask a plumber to detect for leaks you can't see. 

If you need plumbing replaced does your plumber charge you based on a % of rent?
