@Mike D. Don't forget "I am no expert" Just like to give my two cents and keep learning more myself... : )
@Ryder M comments :
I agree this is important to look at. 1. Tax advantages - don't forget you'll be deducting interest, HOA, property mangement fees and other expense so assume a 25% savings (depends on your tax bracket)
I would say keep this cost since you are not working for free if you decide to do it yourself. 2. Cut out that property manager - unless the place is in a rough area or falling apart it's very easy to self manage with something like RentecDirect.com. The key is getting quality tenants which should be easy in a hot market like Denver.
I would need to see the property and get more data to make a comment. 3. Vacancy, CapEx and repairs I'd put at 7% each to be more realistic to my experience (unless the place is a mess or in a bad area).
I would also pass with what I see so far.. Still, I probably would pass on this deal..........
My Numbers:
@Mike D. the numbers I used are from multiple sources but don't forget that it's just a average for the area of Denver. I agree with @Bill S you need to look at the specific areas.
I will usually looked at the data of just a few blocks (see what type of rental competition there is) then move out further from there. I will also call rentals (and go look at them) in the area to see how they answer a list of questions that I have and see how they answer them.
One more comment about one of @Bill S. comments. : )
"Lots and lots of landlords have not kept up with the local market for rents. Don't be surprised to see rents well below market for poorly managed properties with long term tenants."
I know of a couple of Apartment Building & SFH owners that keep there price below the market (not because of being poorly managed) but because of there business strategy. One of there strategies is that they are very choosy about who becomes a tenant in there buildings. Because of the lower prices they receive a higher demand for there properties which in turn allows them to have larger pool of possible tenants to pick from. I am amazed on how long there waiting list is for tenants. In the past when the vacancy rates were higher they have always been 100% full to my knowledge.
Keep using Biggerpocket (and others sites) to continue getting different points of views. It works to your advantage.
Good Luck with the Hunting...
