This would be typical for analyzing large apartment complexes.

Sadly with these low price points many brokers and agents do not care about the buyer or seller as they really are not making any money on the deal.Most of the experienced investors I talk to that have 50,100,150 units do not like all vacant properties.They instead look for the sweet spot.The sweet spot is just when a property is turning downward and they can get for cheap.If you can buy the same 4 unit for 50k and put in 20k to be at 70k then that is better than buying at 25k and putting in 75k and being at 100k.The completely vacant building also doesn't have paying tenants in some units for cash flow while you rehab the others.Of course if the existing tenants are not paying that can be a negative although the property might not be vandalized as much because someone is occupying the space.You have to weigh everything when looking at a property.You really need a local investor to come by and just tell you what you are in for and plan for it to pull out of this.In many cases buying a vacant building and being lured in with a low price can be a BAD DECISION.If you don't want extra risk or doing rentals like this people can form partnerships etc. to go in together to buy higher quality and larger assets.

This is part of the complexity.  

The one I rolled in was hard to refinance because of a high non owner occupancy ratio in the complex (too many renters to owners).I know going forward I will likely have to do shorter loan lengths (because I am over 4) and am fine with that as long as the numbers make sense.I would go with 30 year mortgages with traditional loans when offered on your first 4. 

Sweet.

Just a few hours ago I wrote a brief message explaining that I was interested in buying multi-family real estate (duplex, triplex, fourplex, small apartment complex or mobile home park) and that if they could put me in contact with anyone they knew who wanted to sell such a property.

i was also on a webinar last Thursday.and my current living situation is pretty nice my rent is 1145 for a beautiful 2600 sq ft. home  in the aliente area of las vegas. i rent a room with a jack and jill bathroom to my friend for 550 works 2 jobs and is never home see each other like two or 3 times a week. so its a huge place for 600 a month lol . and yes the house hack is actually  what i planned for for my first investment. i hope to one day have apartment complexes 

I am currently a Work at Home Mom, to a sweet 9 month old boy!

But, if you get many properties it becomes much more feasible.The one owner I know of a LARGE complex just has 2 property managers. 

There are about 3 brand new large mixed use complexes within walking distance, that are renting from between 2200 - 3400 a month (these have pools, fitness rooms, restaurants and bars, all the frills).
