If you can borrow money at 4% and buy a 10 cap, you are essentially getting to enjoy a 6% return on the banks money with little effort!

You can first try different social media platforms first and see which one has the best result and drives more traffic, then you could put more effort on those specific platforms.

My rent collection isn't automated, unfortunately, so collecting late fee requires a slight increment of effort. 

The time, effort, and money involved in converting the 1st floor.

It's been the best move I've ever made, but I was incredibly picky.I m in the same position ,I m planing fly out to OH next month to meet up a local consultant and to partner up with deals, the structure he provided is 50/50, means I invest money ,he invest effort (finding deals /rehab/finding tenants etc.all the heavy lifting )and we share everything, debt /profit/cash flow----50/50, buy and hold for long term on MF rental properties, the properties will be under trust agreement and with his name and my name as beneficiaries.I was still wondering what is the long distance partnership like in nowadays?

I will state that STRs are a lot more effort than Long Term Rentals (LTRs) so you will either need to hire a PM or take on the extra work.

Invest time and effort in finding that agent, it will make everything else so much easier.

But for raw land that is going to take all this work and effort to even see that it works there simply is not a lot of value in what you bring unless the price is a SCREAMING deal and for some reason locals don't have it on their radar ( which is not likely in a market that is robust) 

Since you ask about 100% financing, the ones that I have heard of tend to a) be very expensive like 12-15% plus 5 points, so you already have paid a bit of downpayment whether you know it or not and b) the property goes to an LLC which you can get kicked out of the moment you miss payments - no foreclosure necessary and you lose sum rehab efforts you put in.I recommend that if you use a HML (presumably because conventional financing,  which is cheaper, doesn't work for you for some reason) that you go with ones that want you to have skin in the game to share their risk.Best wishes in your endeavors. 

It would take effort to file the lien and if he isn't even willing to put in effort to save money and buy a place when he is living rent free, it will be too much effort for him.
