Hello, I am interested in buying a small single family house in a decent neighborhood (average median house price around 450k), but the seller would want to sell the land (50x100) next to it together for an extra 100k to make a deal. hypothetically I can negotiate it a lower price for the land (any suggestion on how to determine the value for the land), what kind of investment can I make to turn the land into something profitable rather than just being wasted?

Sorry if I spoil your secret William, “Minimizing your tenants rent without lowering your income” is better known as “Section 8”

Also look at the investment as a place you can safely put cash down and know it will be their if you ever need to exit with a higher return than putting it in a lower yielding investment.  

Pods are rented for $275 which is $75-$150 lower then larger parks within 2-3 miles that are in a nicer park.

We wanted to rent it out on the lower end of the rental market to have constant renters and then the pick of who we would want to rent to. 

Whereas Investors, because they'd be putting down higher deposits and having worse Loan terms, may well be be happy with fully occupied homes (dependent on ROI).More often though, I read of Investors putting in lower offers for homes that are occupied!

This year and following up next year is just paying off unnecessary debt, working on paying off my auto loan, will bring my DTI even lower.

- I think this is a better option than self financing with him at a lower value with added interest to get him to his price just due to time constraints on mortgage term plus the numbers seem to make more sense based on the passive income captured through a good lease deal.- How do I avoid him from selling while under lease?

when I will back the water and sewer bill to the tenants it’ll be even lower. 

He got nothing other than more mortgage payments and lower valued home.
