Some smaller companies charge less and the more income the property will bring, the more they'll reduce that fee.   

Many people are doing wholesaling sucessfully but I feel in the market we are currently in it makes more sense to be an agent and try and earn commissions and then be able to buy houses as a discount / reduced downpayment. 

Incentivize them in a way that works for both of you (fee, partnership, whatever).I hope you can find the answers to increase the revenue and reduce the expenses so you can keep all these properties. 

I find that this is good bargaining tool if issues arise and helps reduce risk.

At least with MFH you might be able to house hack or reduce your rent by having other share the payment of your mortgage.

There's very little that changes in the process other than needing to rely on more people to be there for you when you can't and therefore reducing your potential margins.The hardest parts are finding the properties and financing, and those are the same problems that you're going to find anywhere.

If you work with an agent, take their projections and reduce gross rent by 25% and up the maintenance costs by 15%.

This helps reduce headaches and keeps tenants happy for the long run. 

The HOA does not reduce their bills because your house burned down.

Should I file for an LLC or some other legal business entity to reduce taxes on any income generated from this venture?
