You'll just know you're doing it right. 

You can have a generic ads copy but if you have great video quality and you are hitting all of the pain points in the video, you will start seeing tremendous results. 

Many builders are offering great incentives right now for buying down your rate permanently, and/or paying some/all of your closing costs. 

Lets say if I have 15 years of depreciation in a home left and I installed a new HVAC, can i depreciate the new HVAC system over 15 years or does it have to be 27.5 (a lifetime that exceeds the rental property)? 

But right now, I wonder if a total newbie in this should really be trying to get a small loan (50k) to purchase two house around 60k each?

You need to do the duediligence to make sure you are working with the right ones. 

Quote from @Alecia Loveless: I think you made the right choice.

Covers entire purchase, entire reno, with money left for reserves, and a couple months of vacancy.

The new mortgage on the new $340k duplex home which is an FHA loan is going to be a monthly payment of $2800 and we will refi ASAP (the current rate is 6.7%) when rates go down.We have done some nice improvements on the SFR and will be refinishing the wood floors before a renter moves in (July 1) so feeling like it's a great opportunity for the right long term renter and we plan to screen prospective tenants well.We are taking a $20k HELOC on the SFR for the downpayment and plan to pay that off within 12-18 months.

The beauty with the seller paid is that the money goes into an escrow account and if you refi or sell during the buy down period, the left over funds go towards the principle, so it’s not lost like if you were to buy down the rate with points and then sold/refi in the next few years.Hope that makes sense but let me know if there’s any other considerations or something I misunderstood and we can continue brainstorming!
