This could be a tricky transaction with terms and liens in the property.

I try to avoid this neighbor due to lots of activity of cars coming and going all weekends and week evenings.After much effort and skip tracing I was recently able to locate the out of state owner of the property on the side and promptly sent another certified letter as earlier mentioned.The big problem I may face soon is if I sell this property I may face issues from the buyer or buyers insurance company regarding these trees overgrowth,Short of me digging in my pocket and paying for tree service there is also the issue of contacting the owners requesting permission to access the trees for trimming.

Tenant will continue to pay for utilities and any difference (or loss in rental) if home is leased for lower monthly rent than current lease term. 

Quote from @Brittany Smith: This is a long-term rental.

I feel that I am analyzing deals well in terms of price, downpayment, rents, cashflow, etc...

if you have a long-term tenant, the first question is, how long have they lived in the unit?

Rather, it will be considered earned income... and if you have losses especially the first year with a bunch of start up costs and depreciation... and if your money is at risk (let's assume Yes), then this business venture can offset (or add) to your W-2 income.This is how short-term rental loophole works.

Much less transactional, but more lucrative and fun long term 

If you are trying to build long-term wealth, you may be more focused on appreciation.

If investors do not account for this the likely hood is that they are losing money and the property investment is a waste of both time and effort to hold.
