You have incidental expenses of an extra 3-4k on the rehab maybe.

Your property management should send you pretty clear reports at the end of the year so as to obviate your need for such.If you have more than 3 units and self manage I suggest software - especially if you are considering expanding.I find Stessa usefulI also use buildium but not incredibly thrilled with it.  

The extra $150 will be long forgotten the month after you buy it!

From my understanding, mortgages are considered riskier investments than most other loans because the borrowers can repay early with little to no extra cost.

I went through demos of all of those, pulled together our evaluation criteria, etc. and then ended up choosing Hospitable (which we've been thrilled with).Thanks, that makes much more sense and frankly, is a relief (I started wondering if I was missing something, lol.) 

We’ve also tried talking to the neighbors directly, but they don’t acknowledge the issue or make any effort to address it, on the contrary somtimes they are extra loud in spite. 

Subject to zoning could be apartments, self storage on extra land, sell lots, etc. 

Some things matter more than saving an extra $200/month because you chose to live in a market you didn't necessarily like.

I don’t have any debt besides my mortgage fortunately or unfortunately however you look at it, and I’m not opposed to using my extra funds to buy down my mortgage but I’m afraid it won’t lower my DTI quite enough.

It's easy to obtain, costs very little, and doesn't require extra, on-going effort to maintain.
