If so you must be a purely buy & hold person. 

Investorfuse or Follow-up Boss are purely CRM/Lead management and might be a simpler solution, whereas Podio is much more comprehensive and complex and can be used for a lot more business processes and data management.

Obviously this is purely an opinion with no right or wrong answers, but just want to hear from wholesalers (with at least some success) share which type of motivated sellers they have had the most success. 

Just pure numbers and luck or the lingo you are using in your cards?

This is purely speculative, but I imagine to generate a reliable pipeline of leads in a market like Austin using only a generic mailer, the amount of mail one would need to send is likely on several orders of magnitude greater than 500.

, but do your self a favor and look for local meetups in your area, nothing beats that face to face networking. and you never know who you might meet. there are several in the houston area, some have are pitching goods or services and some are just purely networking events. see what fits your needs best. the one i attended last and made some awesome contacts was the one held by JET Lending. they meet once a month if i remember correctly, they are also members here on BP. good luck and hope to run into you guys at one of the meetups.Nick 

I may be biased as a recent home-buyer and "house hacker" in Bayonne (in addition to being a licensed NJ Realtor), but I think Bayonne offers some great opportunities, not necessarily from a pure rental play, since the taxes are high and it would be challenging to generate solid positive cashflow, but for anyone looking to house-hack (live in one unit, rent out the other, while enjoying a good quality of life, with plenty of upside). 

This is pure speculation on my part, so check with those that actually know, but it seems like more and more hospitals and clinics nationwide are having to contract out due to a shortage of nurses and professionals so the demand seems to be there.  

I would keep your personal bank account for expenses that are definitely not business related, and open a new 'Rental account' for expenses that are purely business. 

Or just purely the fact that it's a hidden gem?
