Relying on income generated by the first few rentals is not only risky, but dangerous.

again, BRRRR is a risky strategy right now, and it just doesn't make any sense for someone to put a significant amount of capital into your first one.if it's a rural area, there are fewer comps. 

There are not many SFRs within $850k in this area, and even fewer multi-families.

Also eliminates any issues with code enforcement if the boys forget to mow the lawn or spray for weeds. 2) Smaller yard / patio = fewer problems with noise complaints (which Tempe has really cracked down on).

Do you find it more profitable to run large numbers of guests through a basically stocked home with a lower rate or fewer guests in a nicer home at a higher rate?  

I would not invest in any city on Neighborhood Scouts’ list of the 100 most dangerous US cities.Metro area population greater than 1 million.

Personally, I think it's dangerous for anyone to stick more than 5% of their assets into in any one deal. 

Fewer, however, said their household income is significantly higher than it was a year ago.With the housing market now in its historically slow winter season, some agents are reporting activity is “frozen.”

I am in any danger of the lender calling in the mortgage since they will have a harder time selling it off without the FHA insurance?

You'd be in danger of negative cash flow AND further loss if you need to sell.
