If such is the case, the tenants in the lower flat will hear the tenants in the upper flat walking around, and kids running around upstairs can amp up that noise.If the flats have a common forced air furnace (or if there are two furnaces in a common basement or attic), muted conversations will make their way between the units.

If it has no central air/heat I assume you’d probably get an extra $1,000 or $2,000 in value?

Air Bnb the other side while you and your friend live in one side so you live free, and after a year you can make both sides medium term rentals and buy something else. 

So, keep in mind what a good tenant expects in your area.For example, if you have an existing GAS furnace and central air conditioning already a simple replacement of the gas furnace gets people what is likely to be an economical heat source while also providing a/c which many rentals don't have.

Bro, if you just add a 4 story addition and rent half of it as an air BNB and the other as a LTR you'll be able to cash flow for surePurchase price: 120kRehab: $500ARV: $7.4M

Unless a guest smokes regularly or heavily, our ventilation and air filtration is such that our cleaners have not yet alerted us to undeniable smoking, etc.Would love to hear what others use and their experiences with Minut as well (since in part, I went with Minut based on what I read here about the other alternative- NoiseAware).

The average cost for an Air Conditioning Refrigerant Pressure Sensor Replacement is between $270 and $288.

I know in Orlando in most areas that don't allow air bnb, will allow you to have an air bnb as long as you live in one side of it while having it as an air bnb. 

If I was in your position I would look to air bnb or VRBO the property you purchase in San Diego this way you will have less negative cash flow than if you were to rent it out to a long term tenant. 

**Air Conditioning:** The AC unit is malfunctioning.2.
