I was able to get interested buyers (investors) under contract, but a couple ended up backing out either due to the appraisal contingency, inspection, or lack of funds which are all common reasons.

I would also ask for the inspection checklist so you can ensure your place will pass inspection. 

It's hard to use hard money on these since you typically need an inspection of some sort. 

Before you do anything, you'd be well served to have an occupancy inspection to see what your municipality will force you to do, before allowing a new person to move in.

I used Lane Home inspections for our last purchase inspection and wasn’t happy.

Does the property inspection support their asset condition evaluation?  

Hello fellow homebuyers,I recently made an offer on a house with an inspection contingency covering the roof, foundation, electrical, plumbing, backyard fencing, and pest infestation.

Make sure you've inspected it, but pay them quickly.

What happens when the city comes to inspect your new HVAC and sees that walls have been opened up to accommodate the same but no building permit was ever pulled?  

You could also reach out to a local, reputable, property management firm to see if they offer a la carte services for lease preparation, application processing, move in inspection, etc, if you are planning to self-manage but need some help with the more formal items.
