Have an air tight offer for the seller but base on what works for you.

If you want to do short term Air BnB the city hasn't ruled it out.

updated kitchen, added central air and gas heat.

check for knob and tube wiring (it can be pretty costly to replace), look @ the basement for foundation issues

We updated all the wiring and added central air to the house as well.

I've never done Air BnB as an investor, but it doesn't sound bad to me - the income you can get would be much higher than a traditional tenant... also more turnover/managing bookings ect - so depends on if the cashflow makes the extra work worth it for you. 

Right Brothers Heating and Air have replaced several HVAC systems for us, and they also do mini splits in older homes.

We'll do business with just about any kind of tenant, but we like advanced manufacturing, construction companies, air freight and flex R&D. 

@Erika RogersBrandon Turner has a video on You Tube called the four square method.This is a great work through to quickly analyze a rental property.

My wife and I have a rental condo in Las Vegas where the water heater is integrated into the central forced air heating system.
