., I charge a one-time non-refundable pet fee of $250 per pet, and I charge a recurring monthly pet fee of $25/month per pet. 

The property has stabilized and is cash flowing at $325/mo after accounting for all recurring holding costs and maintenance expenses.  

I was thinking more along the line of multi-families so I can collect recurring revenue as long as the property is being rented.Thank you and hope to hear back!

If your gross income is high enough to add your PITI payment and still be under 50% DTI without tenants, you're in good shape on that end.Don't forget to allow for vacancies and non-recurring maintenance/repairs!

So if you're making $42k, then that works out to $3500/month and you could use this to support $1260/month in total recurring debt (like car payments, credit cards, and housing). 

You can only allocate a couple % for this - the other regularly recurring expenses like roto rooting, regular tree trimming, asphalt sealing, etc can all be allocated as part of your diligence and be pretty firm year over year.

(But then again, that's one reason the house in in such a beautiful community).Could you have possibly rented this out (or L/O'd it) to recur some expenses?

The goal is to identify single family homes, multi-family homes meeting something recouping costs and recurring costs within 3 years.

Outside of taxes and insurance, I can't think of any recurring major costs. 

I've talked to a few of them, and the recurring theme is they invested for appreciation down there.
