It essentially includes having a buyer for a specific property BEFORE entering  in a contract with a seller.  

But as was mentioned above, you need expertise and experience.For the first 2-3 years of activity investing in real estate, I had to use my own money sources for down payments.

Yes you can use commission as sourced funds for down payment on a conventional loan.However some lenders have internal overlays that don't allow it.

You should consult an attorney or CPA for your specific situation.An LLC is useful for two things: anonymity and legal protection.

Yep - My firm can do this for rate-term refinances and/or acquisitions, with stipulations (specifically for 85% LTV): Min DSCR of 1.25x+, Min FICO of 720+, SFRs.

I'm not specifically familiar with BP's deal analyzer (I use my own).

Does anyone recommend knowledge sources on building a mobile home parks (websites, books, organizations, plans, etc..). 

Quote from @Sri Reddy: I am a newbie to real estate investing and looking for guidance from the teams here to understand the sources from where we can find any small retail spaces to buy.

• Crowd-sourced projects (think Crowdstreet, Fundrise, Roofstock)• Moving into investment for 2 years and sell (seems extreme and low level of confidence in strong desired results.) • BBD - Bulk everything together into one large investment, cash-out refinance, rinse/repeat (seems like ongoing work like we have today.)• NNN - purchase triple net lease opportunity (1031 everything into it, managed under trust, tenant takes care of everything) • Sell each off the normal way (even spreading out one a year, heavy tax implications and truly diminishes decades of work.) • Give/donate each away-----I expect many here have already been through similar dilemmas and interested in experiences, lessons learned.

My posts aren't specifically about Rent to Retirement, rather the concept more generally.I am also not concerned with the new construction turn key model, its very different than the lower tier/entry level SFH's and not relevant.
