I will have to split the address, the previous guy who owned the property and rented it out did not take care of that.

She gave us her address and said it the scariest house on the block.

Write down their email address, and then reach out to them asking for their criteria.

How did you address the tenants who may ask how do you have pets but we can’t?

Invite a property manager in the area for their analysis of the address.

It is your responsibility and if you don't address it you will have a more expensive problem in the near-future.Diagnosing/locating leaks is fairy simple.

Do the following, go to assessor's website of county you live in, locate GIS data organizing properties by number of units, download excel spreadsheet of addresses/owner info, import into google maps using site such as batchgeo, drive by and identify 15-30 properties you're interested in, skip trace owners to find current address, text/email/call owners, be consistent & do this every 1-2 weeks, you find a property in 1-3 months. 

$64k per unit that rents for $640/month with no appreciation will make NO profit. 1% does not work at low rental rates because it does not properly address expenses and cap ex. 

Your lease should address this, since most states have no laws on the books. 

Also shouldn't be happening once fixed and addressed.
