so much so that many contractors use red wood 2x4's as plates for walls being installed directly on concrete, particularly if the concrete is directly on the ground or in a basement. 

I would love to use real estate investing to make anywhere between £1000 - £2000 a month as i also want to use my time to focus on my social media agency.

Ok...I get it...apartment investing is THE best way to use real estate to escape the rat race in a short-ish period of time.

Thank you all for the warm welcome, I am really looking forward to growing my investing and have already found Bigger Pockets and its users to be an excellent resource.

Some of these impact the rent your property can command. 

BP users say "check local suppliers" but it seems we end up at the big box stores every time. 

Backround: This property is a SFH, but due to it being in a college town and consistently rented by students, it commands much higher than market rents ($2500/mo).

Lots of them use Rent to Own furniture and appliances and they abandon, everything.

if it were me, i would put the new trailer in. i'd offer it to the upper end of the blue collars as RTO/LP. whether they exercise the right to buy or not, the "new-ness" can command a higher monthly rent/payment. if you can find someone to put a sizable down payment proving intent on ownership, they ought to treat the property better.3rd option, just offer the lot for rent at $300-$400/mo. they can bring their own trailer. if they ever leave, it should be in the lease that if they leave the home on the lot more than 30 days beyond their move-out date, the trailer becomes your. for free. clean it up and rent it out again. save yourself from spending 30k up front.just make sure your Monthly rent - PITI = cash flow.
