Most of the time, it's not going to be hidden.

Understand the fees involved and calculate the total cost for an entire year of management so you can compare the different managers.

These folks wont tell you not to pay them massive fees! 

You'll also need to show stable income for the past two years through W-2s or tax returns.Talk to 3-5 lenders to compare their rates, fees, and terms.

For example, I mention that every adult must pay a $30 application fee, pass my credit/criminal background, make a combined income of 3x the rent, and whether or not the property accepts pets.

Never heard of a voucher tenant being responsible for maintenance and repairs, rental licensing fees, lead testing upkeep, cap ex, reserves, book keeping and tax prep......and even if you self manage, it takes up your time and should be treated as an expense because its taking away from your ability to earn income elsewhere. 

A follow up question I now have would be do you think its smarter to completely pay off the first property before buying a new property or to keep going out and buying new properties once i have enough saved up for the down payment along with extra fees?

We are pet friendly and have some zeroscape backyards and have wording like "We are pet friendly with a fee, but please note although backyard is fenced there is no grass and certain areas contain crushed shell which could hurt your pets feet". 

Owner ended up settling with the tenant, but then we had to threaten to sue our own client to get them to pay our legal fees.- Owner must sign a Hold Harmless to indemnify us against any potential tenant lawsuits relating to the work their contractor is doing.--- Another lawsuit resulted from owner's contractor taking down basement handrail to get supplies down the steps, then they didn't put it back and tenant fell down the stairs.- We also negotiate a reasonable completion date, depending on the Scope Of Work (SOW). --- Who gets all the phone calls and wastes time calming a tenant down because the owner's contractor doesn't show up as scheduled after they took time off from work or a 3 day job takes 3 weeks?
