The owner reports gross rents of $2750/month (this includes the home plus lot rent). 

I have a few critical questions:1- Do I need permit for kitchen and bathroom remodeling (which includes changing the layout within its boundaries without expanding it)?

When you list your properties, you can include in the listing that you're willing to accept Section 8 applicants. 

We agreed on a section 8 tenant stabilization plan, and after their first full month of taking over, here's how we're doing: Total Properties: 11Total Rent To Collect: $10,240Historically, under Own It Detroit (Mutual Property Management) -- monthly totals of rent collected on the first and before the 5th was typically $1200 LogicPM has inherited tenants who for the past 6-8 months were told as long as payments come in before the end of the month, partial payments included, you're okay.

How does the property do if you use 50% of rent as expenses not including P&I?  

Including a contingency in the first 3 days after the contract is accepted is a good idea especially if there are tenants. 

If you're worried about break-ins, then you need to secure it.We give our clients several options, including removing & storing the mechanicals to avoid theft.Also, check with your municipality to see if they have any requirements.

Some of my leases need to be updated, including increasing security when increasing rent; putting in clear violations (such as tenants using electrical heaters, which is a fire hazard); having a reliable attorney ready should any legal issues arise.

This would also include any new Tenants just as above in sect (f)(1).

If so, have you ever done a buy and hold partnership deal that includes one partner invests and the other lives in as principal residence for 2+years during renovation and manages property until sale?
