I have had a couple of addresses over the years and usually I have used UPS, but lately I have seen a lot of virtual option popping up ... earthmail ... regus ... digital mailroom ... there seem to be quite a few.Would anyone have feedback on the best route to go?  

If this is financing for a stabilized property rate carries more importance but rate combined with origination fees, pre-payment penalty and term in which you intend on keeping the loan in place are all considerations which together should help in deciding the best financing option.

How quickly are you able to save for a down payment?

At $200k I'm guessing you would still cashflow even with such a small down payment. 

A preforeclosure period of 120 days is required before a lender can enter foreclosure for lack of payment. 

Predatory lease option investors know that and do that by design, they will keep the 5k-10k option payment after 12 months and lease/option it to the next family who is chasing after the American dream.

If you want to buy and hold, you will need at least $35K-$40K for the down payment.

I would also consider scaling back major expenses like car payments, lavish shopping, etc.

Mortgage payment of $870 PITI with 20% down at a 7.25% investor rate.

Brickell has that same kind of potential, but with even higher rent ceilings thanks to its location.A couple of things to keep in mind as you dive in:Financing: As a first-time buyer, you might qualify for low down payment programs.
