@Jose Lopez:Repairs and CapEx are way too low. 15% combined is pretty safe.You're forgetting management (10%).Water/sewer is usually paid by the owner of a 4plex.Any other house utilities, like electric for common areas?

Between minor maintenance calls (each at least $100) and the "big ticket" items like roof, siding, washer dryer, dishwasher, oven, etc that will need to be replaced, that will be hard to hit in the first place.

So combine party school with young students and that could have caused trouble for your uncle.

"AUSTIN, Texas — A new concept debuting in Austin combines condo ownership and short-term renting with the city's first high-rise homesharing property.Unit owners will purchase one of the 249 hotel-licensed condos with the intention of listing their unit on the Airbnb platform or independently or through Natiivo management, a new brand by NGD Homesharing.The development planned for 48 East Avenue in the Rainey Street District will feature 33 floors of fully-amenitized and furnished studios, one-bedroom and two bedroom units.

I assume the electricity charge is for the washer/dryer in a storage shed behind the fourplex that is available for tenants.The units are sub-metered, but for whatever reason, current landlord pays for water and gas as well.

I will also strongly encourage you to consider local meetup with Freedom First Real Estate Investor’s Association, LTD (FFREIA) This local group has combination of new, couple of years and seasoned real estate investors.

I currently rent the home I live in because after crunching the numbers aggressively it is more beneficial to rent in my townhouse development here in NJ which was a combined property taxes and HOA fee of $900/Month before mortgage.

They can be a flat fee or a combination of the two. 

Fully stainless and usually the better option in each: electric cooktop instead of coils and 5 burners with heavy grates instead of wire and front load washer dryers.

The other way is to make sure you have good cash-flowing properties with enough equity in them to be able to weather the storm.Or a combination of the two strategies above, which is what I plan on doing.Keep in mind: the average investor who is now all-out 'in it', sinking everything they have into chasing this market will be the first ones to cut, run and cry about how real estate sucks when the market turns and they get their fingers burned.To me, it's better to take some profit when you can, even if by staying in you could have gotten more, rather than staying until too late and losing everything you think you 'made.'
