The brands I've been bid on have been:Eco WindowsCGI Sparta SeriesLawson IndustriesESWindowsAssuraAssura is from home depot, main advantage i've found is that they have a quick lead time of 4 weeks, compared to everyone else saying 6-8 weeks.CGI I heard its a reputable brand with a good warranty Lawson, cheapest quote but Im' hearing has a huge lead time now and they have been messing up peoples orders with sizes or specificationsES Windows, comes from Colombia and I heard spare parts, replacements and customer service is terribleEco, I haven't really heard much about but price seems close to what I'm being quoted for CGI Spartas Anybody on here with more experience that can help me narrow it down? 

We track properties using the customer feature.

I am interested in doing the same as the OP.I can't at the moment but I would recommend you contact lookup a loan broker in your area who specializes in out of the box lending.

Only challenge is there are broker fees and closing costs. 

If you buy a property for $100,000 and then turn around and sell it, you’ll pay ~5.5% ($5500) in agent/broker fees for buyer and seller agent.

Really simple things that should have been easily taken care of by customer service but I could not get them to understand the problem I was encountering and it would take days to get a response.

Failure by the Buyer to so notify the Seller and/or Seller’s Broker in writing, within the calendar days, shall constitute an election by the Buyer to proceed with the transaction.As @Nathan Gesner mentioned, an estoppel agreement is a great thing to get but I have rarely been able to convince a seller to get that from their tenants during a purchase and you could put yourself at a disadvantage when bidding on properties by requiring the seller to get this

They often offer more flexible terms and customized interest rates and repayment schedules.

I am still looking for a VA IRRRLTypical mortgage broker BS.

Basically, I need a whole team: a real estate agent, a loan broker, possibly a property manager, etc.
