I think the before vs after pictures really speak primarily to your experience and ability to execute a project so it can help lenders gain comfort with future projects and allow you demonstrate what level of detail you except out of your contractors.

Knob and tube has more negatives than most people think, As a GC doing lots of remodels in a old beach town, we replaced a ton of these.

Also, focus on 2 years of job/income stability.Class D Properties:Cashflow vs Appreciation: Typically, all cashflow with little, maybe even negative, relative rent & value appreciationVacancy Est: 20%+ should be used to cover nonpayment, evictions & damages.Tenant Pool: majority will have FICO scores under 560 (almost 30% probability of default), little to no good tradelines, lots of collections & chargeoffs, recent evictions.

Quote from @JD Martin: Quote from @Benjamin Weinhart: Speaking to your item #6, I was actually told by the staff here over the phone maybe 5-6 months ago that DMing someone is fine so long as it's not a copy/paste ad and is specific to the individual.

But don't discount a deal killer as negative when they only work in your best interests.

I have non-english speaking tenants, and they registered the tenant portal to pay by ACH (so no fee).

Quote from @Kristian Sexton: @Tanya Maslach Does your lease agreement speak to this?

The major negative experiences for me had to do with ship times (their updates are on the slower side) or what happens if product is damaged or arrives late. 

Speak with lenders early to understand your borrowing power, and explore multifamily properties to maximize your house-hacking potential.

As others have stated, you'll always encounter issues, problems, and complaints (negative reviews) from all sides tenants, landlords, and vendors.The bottom line?
