I know my bank allows automatic transfers of funds without a charge. 

They are saying: explain why we are wrong - or else we will formally charge you. 

For a typical apartment housing 4 tenants with it's own bill, he charges $40 to do the billing.

Great company that are very thorough and charge competitive price. 

@Yuvaraj Vimawala First find yourself a AC that doesn't work for a big company that you can develop a relationship with and you trust to just go take care of any AC repair and charge your a fair price.

If you don't want the restrictions imposed by the IRS when you do an exchange, and if you don't like the need for a trust managed by a third party who oversees your funds and charges you hefty fees for that, consider the monetized installment sale.

Perhaps 625/mo.The other unit is way under charged at 685 for some reason; 3bed, 1 bath, garage.

I have a really good attorney who I use in PDX that wont charge you an arm and a legg and scare you into all sorts of unnecessary and complicated asset protection schemes.. basically you can vest in LLC  have an operating agreement ( that's your JV agreement) and a clear cut buy sell agreement .. pretty simple and standard stuff.. feel free to ping me off line..

if original landlord does not have a move in checklist and inspection report, then you take one when you take ownership. you wont be able to charge for damages prior to your ownership. if there is a report, you can charge for damages (not wear and tear) but be careful if the report is incomplete or not thorough as there is a higher chance you could lose in court if it went that far

You could charge a above market rent, since they are likely desperate, and increase your profit margins while addressing a definite housing issue for these indivulaes.
