If the tenant is claiming to be living in a hotel, she may try to get you to reimburse for that cost unless section 8 has a new process to reimburse them for this... which sounds absurd but I'll let you deduce whether or not you're dealing with someone who is used to paying for things out of their own pocket. 

How much do you net (including financing costs)?

Having used both, I would go with propstream if you're looking for a solid data platform, and are investing significant money into other systems as part of your business and its growth model.

If you drop business and work you can bounce back.  

If they are too busy or too lazy to answer a call or send a short email, what else are they too busy for?

I personally do not prefer to hold high cost SFRs as LTR investments.  

My goal is to wholesale some properties single and multifamily to build some capital while fixing my personal credit and building my business credit.

The only approach I’ve found effective is offering a deposit alternative, which lowers upfront costs for tenants without devaluing your property.

However, you have to be extremely careful financing 100% of the transaction as you still need reserves, closing costs, etc. and make sure it cash flows.You didn't mention if this would be a rental or owner occupied. 

The IRS doesn't trust you to report accurate information, so the 1099 from the property manager is checked against your filing.Any company that does more than $600 in business with you should issue a 1099.
