Looking at the numbers today (keep me honest), I believe you can still find deals with 5-6% yield (current rental state) and hope that it goes up.

I have a renter in there now and am wondering if a cost-seg makes sense to do financially as I am planning to keep the place for 10+ years. 

Keep in mind it is a risk and speculation, if something happens(market tanks, job loss, etc) then you will be out money.

Keep in mind taxes go up as do rents.

That's awesome- I'm glad successful REI's like you are keeping their minds fresh & strong and open for new ideas :) 

@Michael Overall, The length of time that a DST is open is going to keep you from doing this over time like @Jon Taylor said. 

If a nearby hotel is charging $650 per night for a 1000 square foot suite and keeping it occupied, would I not be able to charge the same for a 1921 mansion that sleeps 10 people comfortably?

These are features like online renter payments, tenant portal (for payments and work orders), help keeping track of work orders, tax reporting features, and accounting functionality.

To avoid going through the same poor experience, keep reading.Even if someone give you a referral, don’t make the mistake of assuming that PMC will meet your expectations, just because they met the expectations of the referral source.We also can’t believe how many owners hire the first PMC they speak with!

No but keep track of those repairs as it will add to your cost basis when you go to sell it and have to pay capital gains.
