Hi @Jen Arizmendi, this is a meaty topic here, but I'll unpack a basic concept with Facebook ads and then defer to an expert like CuraytorThere are two types of "ads" on FBA boosted post - a normal post that you post that you pay to promoteAn ad, which is not an existing postFor Facebook Marketing of listings I have spent between $200-450 per listing to market with a combination of Boosted Posts (this is the majority of where the dollars go) and Ads. 

I did a second round, but it was just a boost to a previous fb post that had a few more active views. other than that I will target next just folks over age 45 and up to see the results.

Suppose borrower does not lock because he emails me at 7 pm and I'm not at work.But tomorrow maybe rates get dramatically better because Russia invades Syria and the Dow Jones plummets and Trump actually got elected and everyone on Wall St gets scared and sells stocks to buy safe things like 10 year tnotes and... mortgage backed securities (this is why they are correlated). 

I know investing in an index fund while continuing to add savings would appreciate quickly, but I also know to jumping into REI will fast forward that process dramatically.

My husband and I started  Wholesaler Mastermind and Accountability Call, so we could find more off-market deals by training new wholesalers how to build lists, find phone numbers, create solid mailing, emailing, texting and cold calling campaigns that will boost the effectiveness and likelihood of closing more deals. 

First there are things called pressure tanks you can install inline some where to boost pressure a lot.

My whole goal is to get a buy-in price that's attractive enough that it boosts my margin of safety4) Is there anything about investing in a bank-owned foreclosed residential property that should deter newbies?

They differ dramatically in their rate and terms, so make sure you shop around.

Each one is more dramatic than the previous one.I have learned and survived each one.

This will not only boost your confidence but also help in making informed decisions.
