Why do you want another property right now if you only want it via seller finance?

I reached out to AD lending via the phone number listed on their website, and when I received a call back I wad easily offered personal line of credit and fix & flip loan. 

Why do you need to manage it via an LLC?

What parties to transaction do is still, as it always was, 100% up to them, but they get to do it via the PA's to transaction. 

(We can only get approved via conventional for 330-360)What do you guys think?

It doesn't really matter if you're buying at market value via the TK route, or via MLS because simply owning rental RE over time will naturally build equity through appreciation & debt reduction (not including cash flow or tax benefits). 

Market the property effectively: High quality photos; video; competitive buyer agent compensation; marketing to agents via email, social media, broker Open houses; etc.You and your agent may already have this covered!

Rents have doubled with autopayment mandated via credit cards. 

Hard assets with (extreme) volatility will take out mom & pop; not just via barrier to entry but also by temptation to sell.I have done the following, and I think a few folks have copied me in certain areas and that's you buy the land and offer to re-sell with the condition you anchor the build(3rd party it to a real builder, in my case) for a rent to own or just resell.

I would advise you to hold this for longer then 12 months before you sell so you can have take advantage of paying less tax via capital gains.
