I manage hundreds of rentals and most of them are caulked every 5 - 10 years.

We negotiated a deal with the owner for 20% Equity, we are responsible for infilling the community as well as property management (which we also get paid separately for).

Maintenance is one of the biggest challenges, maybe even #1, in the Property Management industry.Seems maintenance is, Never Fast Enough for Tenants, or Cheap Enough for Owners!

Quote from @Jeffrey Bourque: Hello All, I am new and this is my first attempt at purchasing a property with the intent to create monthly cash flow.The property: Triplex Listed at $140,000 - Total monthly rent income $2,150 - Tenants want to stay and are all willing to sign new leases for 3 years - 8 beds 5 baths and 3,500sqft livable space on a 4,800sqft lot - Heat and electric paid by tenants and water trash paid by owner $180 month - I have managed to talk the selling price down to $105,000 with a kick of $10,000 for closing and commissions so $115,000 all in - Building is in fairly good shape according to pictures and questions but have not done a inspection yet - some general maintenance repairs are needed according to the seller but nothing that seems to bother the tenants. - Taxes are on the higher side at $6,000 yearMy Numbers: $115,000 putting 20% of my money $23,000 and finance the rest with total expense of $1,834Monthly expense numbers: Future Maintenance 13% $273 - Vacancy 5% $105 - Property Insurance 5% $105 - Property Taxes 23% $500 - Property management 10% $215 - Office/Travel/Legal 4% $84 - Mortgage 26% $552 - Monthly Cash Flow - $316 per month or $3,792 per year so Cash on Cash = 17%I think this looks like it is a deal worth doing and I also believe I can bump the total rent up by $50 each tenant which I think make it even better.

Property management is also in place. 

What percentage of gross revenue does an owner typically keep if they do employ a property manager?

Here you are basically hitting it without needing to manage a property in another location.

I stared using this site PropJump.com to find services providers for my 3 properties I own and manage. 

As an owner of single family rentals, it's on me to adequately vett out and keep on top of the performance of my property managers.

Consider starting with house hacking to reduce housing costs while learning property management, or explore mid-term and short-term rentals for steady or higher income.
