Property Management:I have a property management company that has been difficult to get updates from.

A little difficult actually getting in the "door" but found that the customer experience to be decent. 

and i stand by that.STRs, MTRs, seller finance, new construction, deals bought off market by experienced investors - sure, those could all work. but those are much, much more difficult for a brand new investor to buy on deal 1. 

Buying off the MLS is difficult right now.

The VA is quite difficult to work with.

This one is close to 0.7%   In Memphis it’s becoming increasingly difficult.

@Carolyn Guertin investing in Detroit should be done on a block-by-block basis.That's actually difficult to do, so we ranked 104 of Detroit's Neighborhoods on our site as Class A, B, C or D to help investors make better decisions and NOT get ripped off.NEVER try to invest in Detroit using zip codes!

My contractor helps me with some of the more difficult parts of being a landlord like evictions and notices to pay but if I asked him to go to every showing with me he’d tell me I was nuts.

The way to mitigate this risk is by getting a permit to legalize the unit(which may be a bit more difficult) or duplex the unit with digging down the basement to be in compliance with zoning and building codes. 

Having a tenant will limit the usage for many prospects and likely make it difficult to schedule showings.
