I have one property that I bought last year for $475kCurrent value is $520kInterest rate 6.75%loan amount is $352,000 (I put 25% down when I bought it)Monthly P/I escrow is $2680Rents for $2400im debating putting 100k on the loan and recasting it. this will lower the payment roughly $650 a month and will make it cash flow.

Personally I wouldn't use Zillow, I can only imagine they want to introduce a future fee for the service.

Pick your plan, look into the Kansas City area, use market comparisons, check your money power, look into loan options, put together a team, check cash flow, ROI, and Cap Rate, and make your bid after careful checks and talks.

You can charge up to but not more than what the local power company rate is in your area.

Does it make sense to pay a premium for cheap interest rates with seller financing, or would it just be better to put 25% and forget about my 15% criteria and just go for distressed sellers and just get a commercial loan. 

Perhaps a fix and flip due to the higher rate?

You could start BRRRRing houses and maybe that would allow you to buy more and make more cash flow.As for the paying off the mortgages, I would make you minimum payments monthly and when rates go down in years, you could refinance but pay the same amount and that will help you to pay it off sooner while you are left in the same Cash flow position. 

Many leases state that any fees, utilities, etc are "payable as rent".

General question about smokers - Can we charge a flat annual fee to a smoking tenant to run an ozone machine?  

My strategy is to buy and hold these properties, unfortunately I bought this one in January when rates were high.
