I know plenty of landlords rent to one the next day after the other, but that just doesn't align with my strategy of screening for and obtaining the best possible tenants on the front end, so I can reduce the chance of dealing with a bad tenant on the back-end, which I believe is more costly.The red flags to me are 1) an out of state investor who 2) relies on a property manager.

The appraiser will sometimes flag repairs that need to be done prior to the loan funding.

Plant some colorful plants, decorate a little bit, perhaps with a flag or something on the porch to give it color. 

You usually won’t get that from a discount carrier, but the long term growth is worth it. 

I know that may sound like a red flag, but I see these weekly rate hotels in my area and they dont seem to be hurting for business, and they're charging MORE than $200/week too.

I've seen cases where an FHA underwriter goes "wait a minute, the borrower either lied about occupancy intent when they took out the HML, or they are lying to us now, either way this is a giant red flag for fraud." 

Haven't been able to get a straight answer on the motivation yet which is also throwing up a flag.

What are some red flags to look out for?

A negative review on these subject areas could be a red flag.

We opted for coverage without the roof & we still have the coverage with that exclusion to this day.On another property we did have roof coverage & a large limb from somewhere nearby went through it after a bad windstorm, the carrier would NOT cover it.Then again these properties are free & clear so we do not have mortgage underwriters to bother us.
