I'd pay the loan payments with the proceeds if my STR cash flow isn't enough to cover it but just until I can sell each of the units next year. 

This way the tenant rent could pay for part of the renovations as well or the tenant could just reduce your mortgage payment so you gain wealth quicker to keep purchasing properties. 

Currently in the phase of buying my first property and needed some clarification if I’m getting screwed or not I’m in Rome, Ga and that is where I’m purchasing the home it’s a flip that was a 3 bed 1 bath but has been flipped into a 4 bed 2 bath the asking price is $214,900 originally 230k but the seller wants a quick sell my agent told me we should give them the asking price and ask for them to pay 5k closing close I wanted to ask for 190k and same closing cost but agent said they wouldn’t take us serious so I agreed to agents terms as I’m signing paperwork electronically I see closing cost is 17k since seller is paying 5k brings it down too 12k but being in Georgia I am approved for Georgia dream which covers closing and some of down payment now when I sign at closing I have to pay 6k I’m wondering why is closing 17k my friend bought a property his closing cost was only 10k granted he bought his property for 189k but I feel like my agent isn’t really trying to get me a good deal should I back away from this property, find a new agent, go through with this purchase, or am I getting screwed in the process? 

I say it's a bad idea, i'd rather buy different properties and use that money as down payment.

In any case, the interest payments would have to come out of your pocket.Let me be clear.

Landlord shall have the same remedies for the collection of such costs as Landlord has for the non-payment of rent under this Lease.

I run my entire "empire" using Excel/Sheets for tracking expenses, Apartments.com for online payments, MysmartMove for credit/background checks, DocuSign for electronic signing, and Zillow & turbotenant for posting up listings.

If you are looking to start your portfolio you could start off with an FHA loan with as little as 3.5% down payment.  

DSCR loans are based off of down payment, credit score and either actual or market rents so it helps to supercharge an investor's real estate goals and net worth.

I think the end result is the same, but more work with new leases every year.Section 8 leases do not allow the 3 months up front payment approach.
