All are 3 bed 1 bath houses with a 3rd floor That's unfinished was planning on making each a 4 bed 2 bathroom units. 

The house is a fully remodeled 5 bed, 2 bath at 72nd and Pecos in Adams County so I’m wondering if anyone here has experience with Airbnb in this area of Denver, what you are grossing monthly on average and if there are any Adams County rules that restrict Airbnb of non-primary residences (like city of Denver does).

Also, we converted the attic to a 3rd bedroom, but both appraisals only list them as 2 bed (not sure what the FHA laws are regarding SFH and attic bedrooms.)

I feel now is the time to start investing in real estate.My goals are more along the buy and hold lines than flips.

On forums that only track posts and not votes/karma/rep/ whatever they call it I see more of the mega-posters with 30-40,000 posts and folks tend to fall right in line with what that individual says, sometimes suppressing debate. 

The reusability of the credit line just makes it that much more of a player in long term plans.As for pricing I would say you should do that based on your risk tolerances.

If its on the property it has to be certain distances away from the lot lines. 

Bottom line up front: Is it good to get prequalified before I start even talking to an agent and looking at properties? 

Since you're doing a BRRR, a viable strategy is to put all of the rehab costs on these new credit lines.

Usually they under estimate  mosts costs and miss line items all together.
