Have you considered exploring sugar CRM as a potential solution?

I tried a variety of options but reluctantly ended up with Quickbooks.

@Leonida Miraglia   Then what @Kevin Sobilo gave you  for options is it. 

Generally there are three categories of multifamily investment properties – which will greatly determine your loan options.These three categories are based on the number of units at the property.2-4 Units: While these are “multifamily” properties in the sense that there are “multiple units” – you will generally have very similar options for financing to traditional residential loans on single family rentals – think the traditional 30-year fixed rate conventional option or DSCR Loans – and the coveted 20% down payment option too.

Take the time to explore various house hacking techniques and select the one that best fits your objectives and available resources.Good luck!

So what are our options?

Alternatively, you could consider marketing directly to sellers as another option.

Last option, a hard money lender can help.

Also, you didn't mention it but I am also specifically not asking about seller finance, it is an option but not the topic of this thread.

I'm mostly interested in Brussels region, but willing to explore other areas.RegardsMark
