If they vacate due to rent increase you will have costs related to painting and needed updates, and down time for advertising, so pick your battles.. 

This business is cyclical and you want to be able to sustain during the down times. 

I know a few of those guys who either work security in Afghanistan and Iraq or work offshore oil rigs who take their downtime in Asia and sometimes they're over the top even for me but it does annoy me when Americans try not to be Americans just to fit in.  

A single unit/house with no additional units/tenants to help soften the blow from down time will be something you want to be ready for.I just did a search in Denver, CO on Craigslist using the map feature and specified "condo" in the apartment/housing.  

It is tedious, but gives me something to do in my down time.  

Instead of spending time analyzing which funds to park your money in during the downtime, just spend your time looking for new deals and leave it in a simple bond index/money market/savings account .

As far as any downtime, I do recall having to wait 2-3 days for the funds to enter my account, but that was it. 

Was there sticker shock of down time, remediation cost and rebuild?  

@Adam Huntahlers ,  my cousin has a similar job, where he travels around the country with very little down time at his home base.

when you are renting section 8 has very specific guidelines as to how many adults may occupy the rental, and must give their blessing to the changes, they will do income and rental adjustments, but family size v rental amount is protected class, no you may not raise the rent based on family size but .... if there will be too many people to the bedroom count may not be your problem if she adds them to her voucher she may qualify for a larger unit and want to move or HUD may require her to move to a larger unit... she needs to understand she may not have this place to fall back on if her extra family moves out and she returns back to the lower voucher size and cant afford her bigger place, if she is a good tenant and you have a larger place great, HUD will pay more for additional brs not necessarily more people because they also account for extra income which could LOWER hud amountif voucher is for a 2 br it cannot be used for 5 adults and childalthough wear and tear might be an issue to consider try thinking HUD is paying for a br count not # people, you may have down time if she moves out but hud may have a new tenant for you
