There's plenty of investors who would help you for sweat equity or partner up if you put in time and effort. 

Depending on the weather they can sweat , unless they are vented better, the condensation can get things wet . 

Just because the current numbers don't seem to work out to make a deal profitable you can with some CREATIVITY and SWEAT EQUITY make a deal work.

Repeat 15 times a year that's 150-200K sweat equity annually which is pretty good for my level of commitment OOS.

You may not benefit from or provide benefit to the IRA, so sweat equity is a no-no.There are several self-directed plan formats, so get on the phone with a few providers here on BP and see which will best suit your needs. 

I'd find something that I can put some sweat equity into, but hold it for the short or long term. 2.

If you want that larger cash flow then you have to go larger cash in upfront.All in all it's still a good investment but differentiation of cash flow and return on cash depends on what you put in it plus a lot of the factors others have mentioned.Our decision came down to do we want to go heavy finance and little cash in with little cash flow or little finance and heavy cash flow with heavy cash in.We did the latter and works great for us- more stress initially(because it's a lot of cash out lol) but long term we don't sweat the ebb and flow of the market as much as others that have more leverage.Good luck on your journey!

talk about sweating bullets!

My wife and I are trying to put in "sweat equity" right now for all our letters, but don't plan to do that forever. 

I even offered them to make a percentage of the profit on my deals, since they don't have the cash I offered sweat equity.
