@Cali Skier as @Greg Scott mentioned, there doesn't appear to be a lease violation.You could try to be more aggressive about an early termination.Otherwise, just be aggressive on future nonpayment issues.

If they are using 75% of the rental income they are not doing it correctly assuming the rentals you mention are on the tax returns. 

As far as podcasts - it sounds like I am promoting my own here but since someone mentioned them here is a podcast called KC Multifamily Minute and is a weekly show that details all of the on market deals in KC. 

As @Paul De Luca mentioned, no modification is needed.  

It's super user-friendly and their customer service has been helpful whenever I've needed them.I've been using Smarter Contact for about a year now and haven't run into any of the issues that some folks have mentioned.

(especially for those involved on this website)The reason I mention if it matters on this website is because most are real estate investors(long term buy and hold) and will most likely operate at a tax loss which doesn't have an impact on taxes.The second point is, will you invest or not invest in a good investment because of what your tax rate is?

I’ve also spoke with a lender (one lender so far) and they mentioned that some rules have changed and we might not be able to go that route. 

Hi Grayson, with you mentioning conventional 5% down and FHA 3.5% down, it sounds like you are referring to a primary residence.Private Lending/Hard Money Lending is usually on investment property (We can do primaries but it is highly regulated & varies state to state so most refrain from it.)If you are looking to get into a flip, long term loan, whatever it may be.If you have no experience & a solid fico, rule of thumb is 20% down.Hope that helped :)

Don't be discouraged if there is a lot of push back from sellers or agents at first, many of them aren't familiar with seller finance deals or have situations that can't be solved with seller financing (for example, as was mentioned above, they may need a more conventional offer to pay off their house and buy another one).

The $50k-$100k number is for down payments like I mentioned.
