Who can move in the soonest and appears to be the better tenant should be your choice.

Is going to portfolio/commercial lender my only choice?

The tenants will complain, but if you are raising them to market, their only choice is to either pay or vacate and go to another unit with the same rate.  

Success is a process, failure is a choice

Probably not best choice of words, I just meant "financed offers", a person taking out a loan for the purchase.... vs cash.

Then once the property is stabilized with new rent roll you can move towards refinancing into traditional options.

If you are referring to the ability to terminate the tenancy at your discretion sooner, a M2M tenant would generally be the correct choice, but perhaps the wrong approach.

I had some choices for property management that I looked at before I bought the property, but I never ended up contacting them because it looked like I would be using her as my property manager. 

(google search)understand you CANNOT ask extra rent beside the approved amount, and sometimes the voucher may include utilities which means the $1,400 on the voucher may be 250 for utilities and 1,150 for tenant portion + hud.also depending on tenants changing financials and family changes, the % amount paid by hud and tenant may change over time.i would give a call to local office and also find fellow landlords in the area already working with section8 to network with.you want nice,clean, durable but not very base level. section 8 tenants usually have choices so DO NOT BE A SLUMLORD.you are a nice professional provider of quality home solutions for nice tenants!

Which way to go depends on the ROI of each choice.
