Multiple codes so you can track who entered and when based on the code used.

Curious if anyone has a good idea on how to track down a homeowner's phone number?

I'll track down a company who can identify the odor and perform the cleaning and get itemized receipts. 

I do use an online property management software (Rentec Direct) which is great for ACH payments and bookeeping, but I still need someone to keep it updated (e.g. post rents received, input vender/contractor invoices, input taxes & insurance, keep track of late payments, etc.)3.

There are 100% deals but have to prove with track record with most lenders.

My only other complaint is their receipt tracking is a little cumbersome.  

@Gregory Allen Carter if you are new and without a successful track record you are going to need to bring value to the table no matter what otherwise why would someone work with you.

-Have sent several notices (via email/USPS with tracking) to tenant regarding late fees, which tenant continues to ignore and never responds.

How do I record it in QuickBooks and track payments and interest?  

Everyone wants to hit a home run when it comes to multifamily, but it's easy to fail as a property can easily go "off the tracks" when you lack experience or the funds to keep deferred maintenance issues from building up.Find a property that works for you both in terms of financially and physically and remember that this is your first big multifamily purchase, not your last.
