Is there a different way I could make healthy, reliable returns that I should look at?

Due to the poor sterling dollar exchange rate - I have been looking for seller finance deals in the US as my cashflow is pretty healthy.

I've shared some of my favorites below in an effort to provide an initial filter for you.This thread contains a healthy discussion on the merits of various multifamily training programs:https://www.biggerpockets.com/forums/432/topics/40...Here are some great book recommendations on multifamily investing that should help deepen your understanding of the domain:https://www.biggerpockets.com/forums/432/topics/40...Here are some great podcasts that cover multifamily investing.  

I also am researching new construction for multifamily, specifically with green / healthy building materials.

(Smile though, you are getting paid as of the day the lease is signed, it's just not in your bank account yet)- 7-30 days, once the HAP contact is received and you're setup on the monthly auto-pay.

What are some areas/zip codes having more this kind of inventories but still have healthy amount of demand to support the supply?

A mix of both is healthy for most of us (more flips until you get a war chest).For my situation, I like to think of every property I rehab or own as being for rent or sale (even though I plan for 1 option originally). 

Healthy networking and well wishes to you on your REI endeavors.Kudos,Mary

First two steps are:Be a valuable asset to all that you meet, you never know when you will meet the money and it's good practice.Have a solid business plan, utilizing the readily available resources such as public library, SBA and this website among others.By the way, 'valuable' can be attained in a smile, kind word, or nice gesture. 

Have a happy, healthy and prosperous New Year.
