However, seasonality still exists and the summer is low season.

Last week I made a post about getting a US mortgage as a US citizen who lives abroad (https://www.biggerpockets.com/forums/49/topics/1219693-getti...).

And 2, that the property with 100k down will have a 400k mortgage and will net you 5k a year. 

Generally, the builder will also own the mortgage company to recover some of what they give up in credits via the profit on the loan. 

If you sell property 1 you’re basically paying off a 3% mortgage.

We carry no balances and have no car payments and only one mortgage..

I have decided to look into a heloc, I'm a bit newer into realest state investing, I have completed a couple of fix%flips this year, I currently use hard money for the purchase with 10% down and I cover 100% of the rehab, with that said even just doing a couple of homes at a time, I find myself around 200k out of pocket, I think it would be a bit easier on myself and wife if we utilized a heloc vs just cash, my primary should appraise around 1.1m and my mortgage is 640k, I'm looking at pulling about 250k for a heloc, I don't want to refi the home and cash out as I only want to pay interest on funds as I use them ( I know I won't always be using the heloc cash) Any advice or even knowledge for people in a similar situation, and anyone have a referral for a Heloc?

Some old school sellers, like many in here have said, don't even want to waste time waiting for a mortgage and buyers who traditionally get cold feet right after inspection with a big loan.

@Mike Sferacorrect. one small tweak, if you're buying fixer, you wouldn't typically buy with a 'mortgage.' you'd use cash or a hard money loan. 

Their guarantee to cover the mortgage if they don't rent the property is a red flag, too.
