After several weeks the warranty repairman met my sister and looked at the HVAC unit and said there was no leak.

Quote from @Michael Lam: Hi All, I'm an out of state investor looking to start a rental portfolio in the Cleveland area for small multi families (2-8 units).

My Canadian partners and I bought a Class B 144 unit in Houston, Texas for 77k/door and we’re actively looking for another similar deal.

Both flat and percentage base charge usually a 1 month fee to lease out the unit. 

I'd recommend looking at costs. your build cost is going to be well over other homes because of the fixed costs like slab, Hvac, roof, etc. check the market drivers and weight the benefits of short term versus long term. long term is no furniture and help pays mortgage but at this size it doesn't really cover everything. we didn't find a lot of economies of scale in single family detached. can you build more than one unit?

A good broker should be able to tell you a range of rates given specific criteria if you can tell them what kind of deals you are exactly looking at (ex. in central Boston, 10-20 unit, 90%+ occupancy, 30% down).

Back in the US I was constantly looking for multi-family properties but in Barcelona and Valencia I haven't seen any multi-unit opportunities really... 

The offering would be at 490 units at $1000 unit which allows 49% to be sold to have the preceding benefits to remain in place.

House HackersSome owner-occupants are still using the house hacking strategy, where they live in one unit and rent out the other to offset costs.

I'm still focusing on small multi-families mainly 3-4 units.
