Typically on old houses it's cheaper for a seller to put vinyl siding over old asbestos boards then replace and ripoff.

For investment, 20% down is typical with some 15% down options out there but there are restrictions (not sure if this is available for STRs, just LTRs.) 

This typically results in improved cash flow with time.  

The rate will be higher (typically 1% to 1-1/2% higher) but you will be able to sell, refinance, or payoff the loan without  having to worry about paying what could potentially be thousands of dollars in a pre-payment penalty. 

Hi Nick, the 25% down payment is typically standard for investment properties.

It’s a lot of work for a measly 200 dollars a month which is the typical cf on a 60-80k home that rents for 850.

That's more like a typical security deposit to rent an apartment, lol. 

Quote from @Rajagopalarao Paidi: Is there anyway to minimize or avoid agent costs, I don't have much scope for profit if I pay agent costs, what options typically one has Do it FSBO if you want to save them and then hire a TC or company to do the work...

Obviously the net number is what's most important to sellers typically but I have found escaltion clauses and offering free rent backs to the seller are just a couple of ways to make your offer stand out. 

Depending on how much equity in the property would be key as you cannot borrow 100%, if its investment property 80% is max typically.
