The cash flow would be nice, but are you planning to hold for a long term or refinance before the balloon or sell?

I landed on the numbers I did because that makes it cash flow nicely for the buyer in addition to meeting my goals. 

With your additional $100,000, you’d have a nice cushion to renovate or furnish a property like that.It really comes down to how involved you want to be and your long-term goals.

To add to @Ashish Acharya, I would recommend using your retirement funds for notes that earn a nice interest rate, if you're into self directing.Given that you want to purchase a short term rental, I'd highly recommend not doing this within an IRA/401k. 

Thanks,AniFor what it's worth: In my recent audit with the nice man from the IRS, he accepted my deductions of the interest payments on my many SubTo properties, none of which, was  I provided a 1098 by the lenders, because I could show him I was making the payments and how much.

I have noticed a lot of investors are seeking out cities that are offering lower priced lots and simply adding a Modular or Manufactured and capturing a very nice cash flow.There is a new trend starting in Florida and in other states where an investor buys a piece of land or lot and add a 'Tiny Home". 

Its always nice to hear positive things about local people. 

Appliances look nice until the pet hair destroys the fan on your nice stainless steel fridge and you are out another $1k+ to replace it... 

For me as well as the seller.First, you have to define Sub to financing.Do you mean the reckless kind where you overpay for a property, take over the financing and borrow from others to cover closing costs and holding costs when you have no money, no credit, no income, no reserves and can't tell a warranty deed from a deed of trust and you close on the kitchen counteror do you meanbuying below market value, already having a nice income, having reserves, using escrow and title, already understanding the due on sale clause, have done a lot of creative purchases and know when to use and when not to use creative finance and how to recover if something goes amiss?

I'm 2019 I found a nice property on the market that would suit my family really well.
