I can tell you that a BRAND NEW duplex that is being built is being bought by majority of FHA loans; however I still think a investor can make a return since this market will cause a slow down in buying soon basing this off if interest rates go up!

That's $333 a month on a one-year lease, which means you would be better off dropping the price $200 a month and finding a renter quickly.

since you can't actually profit off of it.

I'm working on locking up a property with seller financing and was wondering if I would be able to get a HELOC right off the bat.

now if your rehab is better by 10k and say you shave some holding cost off you might only lose 2 to 3k.. ?? 

Block it off when you want, with a tenant that can afford $750/week and afford to be on vacation. 

If not, then, I don't think it will be a successful partnership.You are better off each doing your own deal and then partnering up in a few years.

We budget for it, so we have it... but can you pull that off?  

STR cleaners generally set rates that average out, meaning the big stays that mess up the whole house are offset by the one offs that use one room and the bathroom and never touch the stove or refrigerator.

So, if you know retail prices in your area, about 10-20% off retail is probably about right.Also, I've done kitchens that were 25 sf and kitchens that were 80+ sf, so giving an average is pretty tough.
