Multiple independent loans at the same time

[Aksel A.]

Greetings everyone and thanks for your help.

Got a question here on the rules to apply for multiple sources of lending simultaneously.

Illustration: Let's consider an investor working on 2 deals A and B at the same time. That is, different properties, brokers, attorneys and especially here different mortgage loan companies or lenders.

As A reaches P&S and start to deeper into closing, does can the investor fully have hands free with B? Can he safely apply for another loan within the same timeframe?

Of is A going to find out about the buyer's involvement (electronically), get concerned about his exposure and call it over-leverage to justify abruptly shutting down the previously approved loan and turning A apart?

Likewise, can a conventional or FHA lender ever accelerate the loan of a leveraged investor or in similar scenarios?

Cordially,
