I'm curious because I'm interested in pursuing voucher-based strategies.

Also I’m curious, though: do you have strategies you rely on to keep projects on schedule, especially with contractors?

Fastest way to learn is by networking with people who are actively doing what you want to be doing in the future 

Lessons learned?

@Karin L Mahmoodi Based on the Georgia Landlord/Tenant Guidebook.

Most lenders are going to want to see a few big things from the ownership group. 1) The borrower will be the enitity (LLC, S-Corp, etc) and any owner with usually 20% or more of ownership in the entity will be expected to guaranty the loan, 2) We'll want to see some experience doing similar projects from at least one of the main owners, 3) We'll want to see bank statements showing liquidity enough to cover the intial cash injection (down payment), the closing cost, and some cash in reserve.

I wouldn't say that people in general like one type over another, but rather people in general cohorts (single, married - no kids, married - with kids, etc.) tend to gravitate towards certain types of properties based on their lifestyles.

You'll learn a ton :)

Wholesaling is definitely a learning process, but here are a few tips to help:1.Build a reliable list of cash buyers.2.Research the areas you want to focus on.3.Get comfortable with contracts and paperwork.4.Focus on negotiating great deals with sellers.5.Stay organized and keep track of your leads.6. 

Try doing a few transactions as an agent before starting this business, you will learn quickly why it will never work.
