It is also a selling/rental point as when I advertised (and my downstairs rental which has great insulation) tenants loved knowing utility bills were low. 

When I think of private money, it's going to be a family member or friend that has money to lend, not someone who advertises or lends as a business  Realtors may know of hard money lenders, or mortgage brokers with sources for non-conventional lending if you or the property cannot qualify for a conventional loan.

I am going to list them:TurboTenantIt is completely free to advertise your rental, screen your tenants.You upload your pictures, write a description and it posts to 20+ websites for freeTakes about 24-48 hours for leads to come in.Once you select a tenant, they pay for the background check, upload documents (paystubs, ID, W2) and it is all set to you.It even helps you build a lease after you select a tenant (there is a $30+ fee for the lease)My referral code .disclosure.

Third, you'll need to start learning what you'll need to do when a unit becomes vacant: evaluate damages to cahrge against SD, lining up handyman to do repairs, taking pics, writing an ad, where to advertise, taking calls for showings, how will you do showings (?)

@Joyce Hall, I have found the following advertise investment HELOCs. 

For those of you with more than 2 or 3 properties, do you advertise them individually or as a collective group? 

Then I asked how much he knew to charge, and the answer was ...whatever I can get away with....he still advertises on TV in DFW to this day. 

If you like real estate like people and have some drive.. you could be at 4k in a year or less.. and then who knows.. if you really hit it good you could be making 100 to 500k within 5 years.. now this assumes you live in a market were prices are not 100k.. more like 300 to 600k per.. and once you get about 5 years in done right you will not have to spend  much on advertising your business will be all referral.. my wife does about 15 million a year all on referral.. but she has been doing it a long time.. of course. so she has a huge clientele base.. some thing to think about.. plus the people you meet in that end tend to be much nicer than dealing with tenants issue and life problems.. 

I've looked at Furnished Finder, Airbnb, Kopa and other means to see what other people are advertising for their units that would be considered good comps. 

And in this market you should have 10-20 applicants within a week at the right price with good advertising.
