Depending on the relationship you have with your tenants, you may get threats, etc. but they don't have any standing against you.Aside from renovating the kitchen:I would definitely have the HVAC checked and serviced by a reputable company in your area.

You could resist it with section 8 after the renovations are complete for more money.

I had remodeled it and put about 9k of HVAC on them and renovate it.

This partner relationship and experience will be far more valuable going forward when you go to acquire larger properties than the value of the “lost“ profits on this first deal.

., which can be 1% to 5% of the purchase price (depending on the current condition).If you are funding the renovations out-of-pocket, you will need to raise that.

You expose yourself to liability (if anything goes wrong) any time you let a tenant do anything significant regarding maintenance - or a minor renovation. 

Also, find a fire damage restoration company, that also does the renovation themselves (the term they'll use is "rebuild" or "recon"). 

I am currently renovating an abandoned church into 4 apartments. 

Either way it’s a small niche.I’d also caution you on you’re maintenance costs. 5 bedroom probably means more bathrooms, a physically larger house with more plumbing, roof tiles, larger hot water heater etc.

How similar is that unit yours is it larger or smaller those are also factors and it’s overall appeal and if it had factors that were better than yours that could help offset the fact it’s in the basement I could still be worth a similar value to your unit .
