I have  been investing since end of 2015- although in fewer platforms than yourself- (Pol, RM, RS, FtF and Acquire. )- On the one hand multiple platforms gives one access to diverse opportunities and there is always something available, but on the other hand the portfolio also begins to become a bit unwieldy to manage.As an investor with experience in so many different platforms it would be interesting to hear your opinion as to comparing their strengths/weakness, advantages/disadvantages.

Any of us who txfr title to LLCs are aware of the slight but technically possible risk).We discovered the hard way this program is no longer available, as we're now stuck with two properties that were rehabbed in an LLC, and now that we're at the end of the 6-month required seasoning, we've been told by no fewer than 6 different lenders that we have to move the properties to our personal names, wait ANOTHER 6 MONTHS, and then refi, if we want to go with a Fannie/Freddie loan.Any brilliant ideas to get around this/move forward without waiting another 6 months with cash tied up and (in the case of one property) a hard money loan racking up major interest?
