or door Alarms?

As a side note and a previous renter who is in your tenants position, try not to disclose that your tenant is the one sounding the alarm on them.

Now, if you absolutely can't get a tenant where your unit is, who has a good credit score, so be it.But, when you start looking for reasons to rent to someone who doesn't actually meet your criteria - this should sound a screaming alarm, at least in your head. 

@Josiah Patrick Zebarth usually my alarm clock.

Also best if seller concessions in the purchase offer include upgraded alarm systems and a panic room.

Snow removal and de icing, require or offer tenant insurance, document applicant refusals or evictions and reasons, require and monitor fire and carbon monoxide alarms, no trespassing signs, tenants only, no subletting, etc etc.  

@Emily RefiWe don't have enough details about your plans, but your phrase "...SD IRA to use for part of a down payment and rehab" is alarming.

Walk through should be done every three months to check all plumbing, windows, doors, furnace/AC, smoke alarms, the entire building.

In that way, If anything alarming came up and was too much for me to handle, I could benefit from the Roofstock 30-day money back guarantee and sell it right back to Roofstock.

You'll also need to hire someone to create as-built drawings for your house (so you can show square footage, locations of smoke alarms, fireplaces, how many beds, etc. and same for your property to show setbacks, easements, parking, locations of trash cans, etc., which you will need to submit to the county with your application.
