Depending on the location you may even be able to air bnb one or more of the units which could potentially produce higher income and less tenant issues.

Air bnb isn’t going to much better with strangers coming and going in your home .

:Ideas so good, they have to be mandatory ;) There's a few of those like clean air acts, clean water acts, DUI laws, health and safety laws...... :)

Facts: Owner listed property at an $85,000 was purchased in 2018 for 41,000 and rehabbed(some) mostly flooring paint and heating and air.  

I would suggest Universal heating and air co.  

Thats why most air BNBs in RSOs have a 21 day limit.

I'm coming off a year and a half of doing renovations to my house myself, with help (from bathroom to kitchen, air ducts to installing windows, tiling to plumbing and electrical).

Plus, development of new attractions underway offers several promising opportunities that remain largely untapped so far.Specifically you should consider Air B n B guest income which could be as much as $200 per night with the right amenities and location. 

Last night we looked at this house and it was from 1953 and NOTHING has ever been replaced except the roof, air conditioner, and water heater.

New appliances, furnace, central air, and roof.
